NAME¶
Smokeping::probes::AnotherSSH - Another SSH probe
SYNOPSIS¶
*** Probes ***
+AnotherSSH
forks = 5
offset = 50%
step = 300
# The following variables can be overridden in each target section
greeting = SSH-Latency-Measurement-Sorry-for-this-logmessage
interval = established
mininterval = 0.5
pings = 5
port = 22
timeout = 5
# [...]
*** Targets ***
probe = AnotherSSH # if this should be the default probe
# [...]
+ mytarget
# probe = AnotherSSH # if the default probe is something else
host = my.host
greeting = SSH-Latency-Measurement-Sorry-for-this-logmessage
interval = established
mininterval = 0.5
pings = 5
port = 22
timeout = 5
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
