DESCRIPTION
This probe measures TacacsPlus authentication latency for SmokePing.
The username to be tested is specified in either the probe-specific or
the target-specific variable `username', with the target-specific one
overriding the probe-specific one.
The password can be specified either (in order of precedence, with the
latter overriding the former) in the probe-specific variable `password',
in an external file or in the target-specific variable `password'. The
location of this file is given in the probe-specific variable
`passwordfile'. See Smokeping::probes::passwordchecker(3pm) for the
format of this file (summary: colon-separated triplets of the form
`<host>:<username>:<password>')
The TacacsPlus protocol requires a shared secret between the server and
the client. This secret can be specified either (in order of
precedence, with the latter overriding the former) in the probe-specific
variable `secret', in an external file or in the target-specific
variable `secret'. This external file is located by the probe-specific
variable `secretfile', and it should contain whitespace-separated pairs
of the form `<host> <secret>'. Comments and blank lines are OK.
The default TacacsPlus authentication type is ASCII. PAP and CHAP are
also available. See the Authen::TacacsPlus documentation for more
information;
The probe tries to be nice to the server and does not send
authentication requests more frequently than once every X seconds, where
X is the value of the target-specific "min_interval" variable (1 by
default).
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
acquisition is initiated. (This variable is only applicable if the
variable 'concurrentprobes' is set in the 'General' section.)
Example value: 50%
passwordfile
Location of the file containing usernames and passwords.
Example value: /some/place/secret
secretfile
A file containing the TacacsPlus shared secrets for the targets. It
should contain whitespace-separated pairs of the form `<host>
<secret>'. Comments and blank lines are OK.
Example value: /another/place/secret
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:
/^influx_.+/
This is a tag that will be sent to influxdb and has no impact on the
probe measurement. The tag name will be sent without the "influx_"
prefix, which will be replaced with "tag_" instead. Tags can be used
for filtering.
Example value: influx_location = In the basement
authtype
The TacacsPlus Authentication type:ASCII(default), CHAP, PAP
Example value: CHAP
Default value: ASCII
mininterval
The minimum interval between each authentication request sent, in
(possibly fractional) seconds.
Default value: 1
password
The password for the user, if not present in the password file.
Example value: test-password
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
The TacacsPlus port to be used
Example value: 49
Default value: 49
secret
The TacacsPlus shared secret for the target, if not present in the
secrets file.
Example value: test-secret
timeout
Timeout in seconds for the TacacsPlus queries.
Default value: 5
username
The username to be tested.
Example value: test-user
This setting is mandatory.
