9/4/2023 0 Comments Splunk enterprise update![]() ![]() ![]() If asset priority is unknown or low and event severity is high, the event urgency is medium.If asset priority is unknown or low and event severity is unknown, low, or medium, the event urgency is low.If event severity is informational, the event urgency is informational, regardless of asset priority.The default results can be overwritten by modifying priority and rank, search syntax, or urgency lookups. This table provides an example of how the urgency values are calculated in notable events by default. You may use the Urgency field to prioritize the investigation of notable events. If both the asset and identity in the notable event have an assigned priority, the higher priority is used to calculate the urgency. The severity value is set directly on the notable that is generated by the correlation search. The following fields are used to determine priority when priority is assigned through an asset and identity lookup: The urgency_lookup determines the urgency level by using both the severity and priority value assigned to the notable that is generated from the correlation search and the priority assigned to specific fields in the assets and identities. StorageEngine : the engine is set to mmapv1 it won't be able to upgrade to 4.How urgency is assigned to notable events in Splunk Enterprise Security We also completed the migration manually of some kvstores to the new wiredTiger engine but forgot to remove the storageEngineMigration=true line from the nf, also run a btool and make sure you don't have the engine hardcoded: splunk btool server list -debug |grep -i engine, wiredTiger is the default in 9.xĪ helpful doc: ~]$ splunk show kvstore-status -verbose |grep -i engine We were prevented from migrating to the new engine: wiredTiger when we didn't have enough storage, once we cleaned up some disk space we were able to go back and run this after the upgrade to 9.x: splunk migrate migrate-kvstore (for standalone nodes), you'll get a message like this if you run it manually:ĮRROR: Not enough space to upgrade KVStore, you will need requiredBytes=102776856576 bytes, but KV Store DB filesystem only has availableBytes=32339398656 $ splunk show kvstore-status -verbose |grep serverVersion Storage Engine hasn't been migrated to wireTiger. You will need requiredBytes=3107201024 bytes, but KV Store DB filesystem only has availableBytes=2286272512 Not enough space to upgrade KVStore (or backup). Migration is not required.Ĭreated version file path=/opt/splunk/var/run/splunk/kvstore_upgrade/versionFile40 Started standalone KVStore update, start_time=" 15:21:46". Starting migrate-kvstore.Ĭreated version file path=/opt/splunk/var/run/splunk/kvstore_upgrade/versionFile36 Lastly trying to understand the difference in the output of mongo versionsbetween kvstore-status command versus splunk cmd mongod -version, clearly pulling from two different places. The above link is for upgrading mongo in a cluster but not on a single instance, when looking at the options in splunk help kvstore I don't see anything for upgrading mongo either for a single instance, tried splunk start-shcluster-upgrade kvstore -version 4.2 -isDryRun true but of course it detected it wasn't a searchhead cluster. ![]() We have since fixed the disk space issue and were able to complete the engine migration to wiredTiger, however don't know how to bump up the mongo version to 4.2. During the Splunk Enterprise upgrade the migration to wiredTiger failed due to lack of disk space, the upgrade still continued and made the first hop of the mongo upgrade from version 3.6 to 4.0, it looks like after version 4.0 it tried to do the engine migration but couldn't because the lack of available disk space and therefore didn't do the last hop to version 4.2 of mongo. Looking to see how to upgrade mongo from 4.0 to 4.2 on a single instance deployment. Upgraded Splunk Enterprise version 9.0.0 from 8.2.5 ![]()
