...
- the number of revisions to keep, controlled by the property
keep_last
, - and the maximum age of a revision, controlled by the property
purge_older_than
.
To explicitely explicitly disable keep_last
or purge_older_than
simply set the value to 0.

Inheritance, Setting up defaults
There are three levels of purging policy:
- Global
- Command Set
- Command
Global
You can set a global default purging policy in conf/opCommon.nmis
:
Code Block |
---|
'opconfig' => { ... 'opconfig_purging_keep_last' => 100, # keep 100 most recent revisions 'opconfig_purging_purge_older_than' => 31536000, # purge revsrevisions older than 1 year 'opconfig_purging_autoprotect_first_revision' => 'true', # protect the first revision by default |
Command Set
You can extend or overrule that default for a whole command set, in in conf/command_sets.d/{vendor-name}.nmis
:
Code Block |
---|
'IOS_HOURLY' => { # command set name ... 'purging_policy' => { 'keep_last' => 1000, 'purge_older_than' => 2592000, # 30 days 'autoprotect_first_revision' => 'true', }, |
This example overrules all the global defaults for all commands in the IOS_HOURLY set, with a shorter retaining period (but a higher number of minimum entries).
Command
Finally, you can also set a purging policy for a single command in a command set only, again overriding any of the command set or the global defaults. Here is such an example, again configured in in conf/command_sets.d/{vendor-name}.nmis
:
Code Block |
---|
'TS_LINUX_PROCESSES' => { # command set name ... 'commands' => [ { 'multipage' => 'true', 'privileged' => 'true', 'command' => 'ps -ef', # command 'keep_last' => 0, 'purge_older_than' => 86400, 'tags' => [ 'troubleshooting', 'operatingsystem' ], }, ], }, |
This example makes sure that for the command "ps -ef
" in the TS_LINUX_PROCESSES command set, only the last day's revisions are kept, regardless of any global defaults policy or policy for the TS_LINUX_PROCESSES set. Note that keep_last
needs to be disabled explicitely explicitly here, or the defaults for this setting would be inherited.
