Enabling the Feature

To enable the Archive Loggin Logging feature, open the `opCommon.json` file and set the configuration option `log_archive_enabled` to `true`.

...

1. Open the configuration file `EventListRules.json` at `/usr/local/omk/conf/`
2. Under the `archiveList` block, define the rules with two keys (see the illustration below):
   • archive - the name opEvents uses 

   • regex - a Perl-style regular expression used to match log entries

     Code Block
     language js title /usr/local/opmojoomk/conf/EventListRules.json
     "archiveList" : { "30" : { "regex" : "Node (Up|Down)", "archive" : "NodeEvents" }, "20" : { "archive" : "SoftwareErrorArchive", "regex" : "INVMEMINT|MALLOCFAIL" }, "10" : { "archive" : "SyslogArchive", "regex" : "SYS-[0123]-\\w+" } }

     
     

     Info
     The list of rules is sorted by keys; for instance, rule 10 will run before rule 20.

     
     

3. In the `opCommon.json`, specify the length of time you want to retain the archived logs.  

   Code Block
   "opevents_archivelogs_purge_older_than" : "365d"

   
   

4. Save the files.
