DESCRIPTION

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%

packetsize

The (optional) packetsize option lets you configure the packetsize for the pings sent.

Default value: 100

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

timeout

How long a single 'ping' takes at maximum

Example value: 15

Default value: 5

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

eospass

The eospass option allows you to specify the password for the username specified with the option eosuser.

Example value: password

This setting is mandatory.

eosuser

The eosuser option allows you to specify a username that has ping capability on the EOS Device.

Example value: user

This setting is mandatory.

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

psource

The (optional) psource option specifies an alternate IP address or Interface from which you wish to source your pings from. Routers can have many many IP addresses, and interfaces. When you ping from a router you have the ability to choose which interface and/or which IP address the ping is sourced from. Specifying an IP/interface does not necessarily specify the interface from which the ping will leave, but will specify which address the packet(s) appear to come from. If this option is left out the EOS Device will source the packet automatically based on routing and/or metrics. If this doesn't make sense to you then just leave it out.

Example value: 192.168.2.129

source

The source option specifies the EOS device that is going to run the ping commands. This address will be used for the ssh connection.

Example value: 192.168.2.1

This setting is mandatory.

unpriv

If the account is unprivileged, specify the 'unpriv' option. You must also configure "pings = 5", since that is the only value supported, and values specified for packetsize or psource are ignored.

Example value: 1
