DESCRIPTION
Latency measurement using SSH. This generates Logfile messages on the other Host, so get permission from the owner first!VARIABLES
Supported probe-specific variables:- forks
-
Run this many concurrent processes at maximum
Example value: 5
Default value: 5
- offset
-
If you run many probes concurrently you may want to prevent them from
hitting your network all at the same time. Using the probe-specific
offset parameter you can change the point in time when each probe will
be run. Offset is specified in % of total interval, or alternatively as
'random', and the offset from the 'General' section is used if nothing
is specified here. Note that this does NOT influence the rrds itself,
it is just a matter of when data acqusition is initiated.
(This variable is only applicable if the variable 'concurrentprobes' is set
in the 'General' section.)
Example value: 50%
- step
-
Duration of the base interval that this probe should use, if different
from the one specified in the 'Database' section. Note that the step in
the RRD files is fixed when they are originally generated, and if you
change the step parameter afterwards, you'll have to delete the old RRD
files or somehow convert them. (This variable is only applicable if
the variable 'concurrentprobes' is set in the 'General' section.)
Example value: 300
Supported target-specific variables:
- greeting
-
Greeting string to send to the SSH Server. This will appear in the Logfile.
Use this to make clear, who you are and what you are doing to avoid confusion.
Also, don't use something that is a valid version string. This probe assumes that the connection gets terminated because of protocol mismatch.
Default value: SSH-Latency-Measurement-Sorry-for-this-logmessage
- interval
-
The interval to be measured. One of:
-
- connect
- Interval between connect() and the greeting string from the host.
- established
- Interval between our greeting message and the end of the connection because of Protocol mismatch. This is the default.
- complete
- From connect() to the end of the connection.
-
Default value: established
-
- mininterval
-
Minimum interval between the start of two connection attempts in (possibly fractional) seconds.
Default value: 0.5
- pings
-
How many pings should be sent to each target, if different from the global
value specified in the Database section. Note that the number of pings in
the RRD files is fixed when they are originally generated, and if you
change this parameter afterwards, you'll have to delete the old RRD
files or somehow convert them.
Example value: 5
- port
-
Connect to this port.
Default value: 22
- timeout
-
Timeout for the connection.
Default value: 5
