DESCRIPTION

Xymon programs use multiple environment variables beside the normal set of variables. The environment definitions are stored in the ~Xymon/server/etc/hobbitserver.cfg file. Each line in this file is of the form NAME=VALUE and defines one environment variable NAME with the value VALUE.

GENERAL SETTINGS

BBSERVERHOSTNAME

The fully-qualified hostname of the server that is running Xymon.

BBSERVERWWWNAME

The hostname used to access this servers' web-pages, used to construct URL's in the Xymon webpages. Default is the BBSERVERHOSTNAME.

BBSERVERIP

The public IP-address of the server that is running Xymon.

BBSERVEROS

A name identifying the operating system of the Xymon server. The known names are currently "linux", "freebsd", "solaris", "hpux", "aix" and "osf".

FQDN

If set to TRUE, Xymon will use fully-qualified hostnames throughout. If set to FALSE, hostnames are stripped of their domain-part before being processed. It is highly recommended that you keep this set to TRUE. Default: TRUE.

BBLOGSTATUS

Controls how the HTML page for a status log is generated. If set to DYNAMIC, the HTML logs are generated on-demand by the bb-hostsvc.cgi(1) script. If set to STATIC, you must activate the hobbitd_filestore(8) module (through an entry in the hobbitlaunch.cfg(5) file) to create and store the HTML logs whenever a status update is received. Setting "BBLOGSTATUS=STATIC" is discouraged since the I/O load on the Xymon server will increase significantly.

PINGCOLUMN

Defines the name of the column for "ping" test status. The data from the "ping" test is used internally by Xymon, so it must be defined here so all of the Xymon tools know which column to watch for this data. The default setting is PINGCOLUMN=conn.

INFOCOLUMN

Defines the name of the column for the "info" pages.

TRENDSCOLUMN

Defines the name of the column for the RRD graph pages.

RRDHEIGHT

The default height (in pixels) of the RRD graph images. Default: 120 pixels.

RRDWIDTH

The default width (in pixels) of the RRD graph images. Default: 576 pixels.

TRENDSECONDS

The graphs on the "trends" page show data for the past TRENDSECONDS seconds. Default: 172800 seconds, i.e. 48 hours.

HTMLCONTENTTYPE

The Content-type reported by the CGI scripts that generate web pages. By default, this it "text/html". If you have on-line help texts in character sets other than the ISO-8859-1 (western european) character set, it may be necessary to modify this to include a character set. E.g.

   HTMLCONTENTTYPE="text/html; charset=euc-jp"
for a Japanese character sets. Note: Some webservers will automatically add this, if configured to do so.

HOLIDAYS

Defines the default set of holidays used if there is no "holidays" tag for a host in the bb-hosts file. Holiday sets are defined in the hobbit-holidays.cfg(5) file. If not defined, only the default holidays (those defined outside a named holiday set) will be considered as holidays.

WEEKSTART

Defines which day is the first day of the week. Set to "0" for Sunday, "1" for Monday. Default: 1 (Monday).

DIRECTORIES

BBSERVERROOT

The top-level directory for the Xymon installation. The default is the home-directory for the user running Xymon.

BBSERVERLOGS

The directory for the Xymon's own logfiles (NOT the status-logs from the monitored hosts).

BBHOME

The Xymon server directory, where programs and configurations are kept. Default: $BBSERVERROOT/server/ .

BBREP

Directory for Xymon availability reports. The $BBREPURL URL must map to this directory. Note also that your webserver must have write-access to this directory, if you want to use the bb-rep.cgi(1) CGI script to generate reports on-demand. Default: $BBHOME/www/rep/

BBSNAP

Directory for Xymon snapshots. The $BBSNAPURL URL must map to this directory. Note also that your webserver must have write-access to this directory, if you want to use the bb-snapshot.cgi(1) CGI script to generate snapshots on-demand. Default: $BBHOME/www/snap/

BBVAR

Directory for all data stored about the monitored items. Default: $BBSERVERROOT/data/

BBLOGS

Directory for storing the raw status-logs. Not used unless "hobbitd_filestore --status" is running, which is discouraged since it increases the load on the Xymon server significantly. Default: $BBVAR/logs/

BBHTML

Directory for storing HTML status-logs. Not used unless "hobbitd_filestore --status --html" is running, which is discouraged since it increases the load on the Xymon server significantly. Default: $BBHOME/www/html/

BBHIST

Directory for storing the history of monitored items. Default: $BBVAR/hist/

BBHISTLOGS

Directory for storing the detailed status-log of historical events. Default: $BBVAR/histlogs/

SETTINGS FOR SENDING MESSAGES TO HOBBIT

BBDISP

The IP-address used to contact the hobbitd(8) service. Used by clients and the tools that perform network tests. Default: $BBSERVERIP

BBDISPLAYS

List of IP-adresses. Clients and network test tools will try to send status reports to a Xymon server running on each of these adresses. This setting is only used if BBDISP=0.0.0.0.

PAGELEVELS

Compatibility setting for Big Brother: List of colors that are considered "critical" and therefore will trigger an alert. Not used by Xymon.

BBPAGE

Compatibility setting for Big Brother: This is the IP-address of the server where a BBPAGER service is running. It is not used by Xymon.

BBPAGERS

Compatibility setting for Big Brother: List of servers running the BBPAGER service, used if BBPAGE=0.0.0.0. It is not used by Xymon.

BBPORT

The portnumber for used to contact the hobbitd(8) service. Used by clients and the tools that perform network tests. Default: 1984.

DOCOMBO

Compatibility setting for Big Brother. Controls whether so send combo-messages or not. Ignored by Xymon.

BBMAXMSGSPERCOMBO

The maximum number of status messages to combine into one combo message. You may need to lower this number of your BBDISPLAY server has trouble keeping up with the incoming status messages from bbtest-net. Default: 100.

BBSLEEPBETWEENMSGS

Length of a pause introduced between each successive transmission of a combo-message by bbtest-net. You may have to increase this value to give your BBDISPLAY server time to process one combo message before the next one arrives. This number defines how many microseconds to wait between the messages. Default: 0 (send messages as quickly as possible).

HOBBITD SETTINGS

ALERTCOLORS

Comma-separated list of the colors that may trigger an alert-message. The default is "red,yellow,purple". Note that alerts may further be generated or suppresed based on the configuration in the hobbit-alerts.cfg(5) file.

OKCOLORS

Comma-separated list of the colors that may trigger a recovery-message. The default is "green,clear,blue".

ALERTREPEAT

How often alerts get repeated while a status is in an alert state. This is the default setting, which may be changed in the hobbit-alerts.cfg(5) file.

BBGHOSTS

Controls how status messages from unknown hosts (i.e. hosts not listed in the bb-hosts file) are handled.

BBGHOSTS=1: Causes the status report to be silently discarded. This is the default behaviour in Xymon.

BBGHOSTS=2: Discards the status report, but keep track of the hostname and report it on the hobbitd status page.

When BBGHOSTS is set to 1 or 2, the hostnames in incoming status-messages is matched without any case-sensitivity, unlike normal Big Brother which is case-sensitive in hostnames. So with BBGHOSTS set to 1 or 2, "WWW.FOO.COM" and "www.foo.com" are considered to be the same host. If necessary, the incoming hostname will be changed to match the way it is written in the bb-hosts file, changing case as needed.

MAXMSG_STATUS

The maximum size of a "status" message in kB, default: 256. Status messages are the ones that end up as columns on the web display. The default size should be adequate in most cases, but some extension scripts can generate very large status messages - close to 1024 kB. You should only change this if you see messages in the hobbitd log file about status messages being truncated.

MAXMSG_CLIENT

The maximum size of a "client" message in kB, default: 512. "client" messages are generated by the Xymon client, and often include large process-listings. You should only change this if you see messages in the hobbitd log file about client messages being truncated.

MAXMSG_DATA

The maximum size of a "data" message in kB, default: 256. "data" messages are typically used for client reports of e.g. netstat or vmstat data. You should only change this setting if you see messages in the hobbitd log file about data messages being truncated.

MAXMSG_NOTES

The maximum size of a "notes" message in kB, default: 256. "notes" messages provide a way for uploading documentation about a host to Xymon; it is not enabled by default. If you want to upload large documents, you may need to change this setting.

MAXMSG_STACHG

The maximum size of a "status change" message in kB, default: Current value of the MAXMSG_STATUS setting. Status-change messages occur when a status changes color. There is no reason to change this setting.

MAXMSG_PAGE

The maximum size of a "page" message in kB, default: Current value of the MAXMSG_STATUS setting. "page" messages are alerts, and include the status message that triggers the alert. There is no reason to change this setting.

MAXMSG_ENADIS

The maximum size of an "enadis" message in kB, default: 32. "enadis" are small messages used when enabling or disabling hosts and tests, so the default size should be adequate.

MAXMSG_CLICHG

The maximum size of a "client change" message in kB, default: Current value of the MAXMSG_CLIENT setting. Client-change messages occur when a status changes color to one of the alert-colors, usually red, yellow and purple. There is no reason to change this setting.

HOBBITD_HISTORY SETTINGS

BBALLHISTLOG

If set to TRUE, hobbitd_history(8) will update the $BBHIST/allevents file logging all changes to a status. The allevents file is used by the bb-eventlog.cgi(1) tool to show the list of recent events on the BB2 webpage.

BBHOSTHISTLOG

If set to TRUE, hobbitd_history(8) will update the host-specific eventlog that keeps record of all status changes for a host. This logfile is not used by any Xymon tool.

SAVESTATUSLOG

If set to TRUE, hobbitd_history(8) will save historical detailed status-logs to the $BBHISTLOGS directory.

HOBBITD_ALERT SETTINGS

MAIL

Command used to send alerts via e-mail, including a "Subject:" header in the mail. Default: "mail -s"

MAILC

Command used to send alerts via e-mail in a form that does not have a "Subject" in the mail. Default: "mail"

SVCCODES

Maps status-columns to numeric service-codes. The numeric codes are used when sending an alert using a script, where the numeric code of the service is provided in the BBSVCNUM variable.

HOBBITD_RRD SETTINGS

TEST2RRD

List of "COLUMNNAME[=RRDSERVICE]" settings, that define which status- and data-messages have a corresponding RRD graph. You will normally not need to modify this, unless you have added a custom TCP-based test to the bb-services file, and want to collect data about the response-time, OR if you are using the hobbitd_rrd(8) external script mechanism to collect data from custom tests. Note: All TCP tests are automatically added.

This is also used by the bb-hostsvc.cgi(1) script to determine if the detailed status view of a test should include a graph.

GRAPHS

List of the RRD databases, that should be shown as a graph on the "trends" column.

NORRDDISKS

This is used to disable the tracking of certain filesystems. By default all filesystems reported by a client are tracked. In some cases you may want to disable this for certain filesystems, e.g. database filesystems since they are always completely full. This setting is a regular expression that is matched against the filesystem name (the Unix mount-point, or the Windows disk-letter) - if the filesystem name matches this expression, then it will not be tracked by Xymon.
Note: Setting this does not affect filesystems that are already being tracked by Xymon - to remove them, you must remove the RRD files for the unwanted filesystems from the ~xymon/data/rrd/HOSTNAME/ directory.

RRDDISKS

This is used to enable tracking of only selected filesystems (see the NORRDDISKS setting above). By default all filesystems are being tracked, setting this changes that default so that only those filesystems that match this pattern will be tracked.

BBTEST-NET NETWORK TEST SETTINGS

BBLOCATION

If this variable is defined, then only the hosts that have been tagged with "NET:$BBLOCATION" will be tested by the bbtest-net tool.

CONNTEST

If set to TRUE, the connectivity (ping) test will be performed.

IPTEST_2_CLEAR_ON_FAILED_CONN

If set to TRUE, then failing network tests go CLEAR if the conn-test fails.

NONETPAGE

List of network services (separated with <space>) that should go yellow upon failure instead of red.

BBROUTERTEXT

When using the "router" or "depends" tags for a host, a failure status will include text that an "Intermediate router is down". With todays network topologies, the router could be a switch or another network device; if you define this environment variable the word "router" will be replaced with whatever you put into the variable. So to inform the users that an intermediate switch or router is down, use BBROUTERTEXT="switch or router". This can also be set on a per-host basis using the "DESCR:hosttype:description" tag in the bb-hosts(5) file.

NETFAILTEXT

When a network test fails, the status message reports "SERVICENAME not OK". The "not OK" message can be changed via this variable, e.g. you can change it to "FAILED" or customize it as you like.

FPING

The command used to run the hobbitping(1) tool for the connectivity test. (The name FPING is due to the fact that the "fping" utility was used until Xymon version 4.2). This may include suid-root wrappers and hobbitping options. Default: "hobbitping"

TRACEROUTE

Defines the location of the "traceroute" tool and any options needed to run it. traceroute it used by the connectivity test when the ping test fails; if requested via the "trace" tag, the TRACEROUTE command is executed to try to determine the point in the network that is causing the problem. By default the command executed is "traceroute -n -q 2 -w 2 -m 15" (no DNS lookup, max. 2 probes, wait 2 seconds per hop, max 15 hops).

If you have the mtr(8) tool installed - available from http://www.bitwizard.nl/mtr/ - I strongly recommend using this instead. The recommended setting for mtr is "/usr/sbin/mtr -c 2 -n --report" (the exact path to the mtr utility may be different on your system). Note that mtr needs to be installed suid-root on most systems.

NTPDATE

Defines the ntpdate(1) program used for the "ntp" test. Default: "ntpdate"

RPCINFO

Defines the rpcinfo(8) program used for "rpc" tests. Default: "rpcinfo"

BBGEN WEBPAGE GENERATOR SETTINGS

HOBBITLOGO

HTML code that is inserted on all standard headers. The default is to add the text "Xymon" in the upper-left corner of the page, but you can easily replace this with e.g. a company logo. If you do, I suggest that you keep it at about 30-35 pixels high, and 100-150 pixels wide.

MKBBLOCAL

The string "Pages hosted locally" that appears above all of the pages linked from the main Xymon webpage.

MKBBSUBLOCAL

The string "Subpages hosted locally" that appears above all of the sub-pages linked from pages below the main Xymon webpage.

MKBBREMOTE

The string "Remote status display" that appears about the summary statuses displayed on the min Xymon webpage.

MKBBTITLE

HTML tags designed to go in a <FONT> tag, to choose the font for titles of the webpages.

MKBBROWFONT

HTML tags designed to go in a <FONT> tag, to choose the font for row headings (hostnames) on the webpages.

MKBBCOLFONT

HTML tags designed to go in a <FONT> tag, to chose the font for column headings (test names) on the webpages.

MKBBACKFONT

HTML tags designed to go in a <FONT> tag, to chose the font for the acknowledgement text displayed on the status-log HTML page for an acknowledged status.

ACKUNTILMSG

When displaying the detailed status of an acknowledged test, Xymon will include the time that the acknowledge expires using the print-format defined in this setting. You can define the timeformat using the controls in your systems strftime(3) routine, and add the text suitable for your setup.

BBDATEFORMAT

On webpages generated by bbgen, the default header includes the current date and time. Normally this looks like "Tue Aug 24 21:59:47 2004". The BBDATEFORMAT controls the format of this timestamp - you can define the format using the controls in the strftime(3) routine. E.g. to have it show up as "2004-08-24 21:59:47 +0200" you would set BBDATEFORMAT="%Y-%m-%d %H:%M:%S %z"

HOLIDAYFORMAT

How holiday dates are displayed. The default is "%d/%m" which show the day and month. American users may want to change this to "%m/%d" to suit their preferred date-display style. This is a formatting string for the system strftime(3) routine, so any controls available for this routine may be used.

MKBB2COLREPEAT

Inspired by Jeff Stoner's col_repeat_patch.tgz patch, this defines the maximum number of rows before repeating the column headings on a webpage. This sets the default value for the bbgen(1) "--maxrows" option; if the command-line option is also specifed, then it overrides this environment variable. Note that unlike Jeff's patch, bbgen implements this for both the bb2.html page and all other pages (bb.html, subpages, bbnk.html).

SUMMARY_SET_BKG

If set to TRUE, then summaries will affect the color of the main Xymon webpage. Default: FALSE.

DOTHEIGHT

The height (in pixels) of the icons showing the color of a status. Default: 16, which matches the default icons.

DOTWIDTH

The width (in pixels) of the icons showing the color of a status. Default: 16, which matches the default icons.

CLIENTSVCS

List of the status logs fed by data from the Xymon client. These status logs will - if there are Xymon client data available for the host - include a link to the raw data sent by the client. Default: cpu,disk,memory,procs,svcs.

BBRSSTITLE

If defined, this is the title of the RSS/RDF documents generated when bbgen(1) is invoked with the "--rss" option. The default value is "Xymon Alerts".

WMLMAXCHARS

Maximum size of a WAP/WML output "card" when generating these. Default: 1500.

BBMKBB2EXT

List of scripts to run as extensions to the BB2 page. Note that two scripts, "eventlog.sh" and "acklog.sh" are handled specially: They are handled internally by bbgen, but the script names must be listed in this variable for this function to be enabled.

BBHISTEXT

List of scripts to run as extensions to a history page.

BBREPWARN

Default threshold for listing the availability as "critical" (red) when generating the availability report. This can be set on a per-host basis with the WARNPCT setting in bb-hosts(5). Default: 97 (percent)

BBGENREPOPTS

Default bbgen options used for reports. This will typically include such options as "--subpagecolumns", and also "--ignorecolumns" if you wish to exclude certain tests from reports by default.

BBGENSNAPOPTS

Default bbgen options used by snapshots. This should be identical to the options you normally used when building Xymon webpages.
