Updates for Moogsoft Enterprise v8.x

MOOG-17273: The new Related Changes tab in the Situation Room lets you view any scheduled maintenance windows, both current and historic, which may have impacted a Situation.

If a maintenance window appears to have impacted a Situation, the window can be flagged to associate it with the Situation for collaborative and reference purposes. This will add a Thread Entry to the Situation to indicate this has been done, and mark it as a 'Resolving Thread Entry'.

It is also possible to un-mark a window as Impacting, which will also add a corresponding Thread Entry, but will un-mark the previous Thread entry as a 'Resolving Step'.

The feature can be configured to allow wider or more narrow time windows for ensuring Situations are covered by the possible Maintenance windows around the same time period.

This feature can be enabled by selecting it under Settings -> System -> Labs

MOOG-17478: Opensearch is now the default Search application used by Moogsoft Enterprise. For fresh installs and upgrades it is deployed. Authentication is enabled by default. The ${MOOGSOFT_HOME}/bin/utils/moog_init_search.sh script has a new flag for installing it (-i) which will change the default Opensearch admin/admin account password (the new one is printed to the terminal), and it configures a new user in Opensearch which Apache-Tomcat and MoogFarmD will use to connect with (this user is put into $MOOGSOFT_HOME/config/system.conf)

For RPM/tarball upgrades involving a migration to Opensearch, it is required to run a full re-index using the moog_indexer utility (instructions provided in the upgrade/patch documentation) after the upgrade.

For RPM upgrades, it is possible to remain with Elasticsearch, but this will not be supported, and eventually a new version of Opensearch will be released which may break API/index compatibility, at which point it will be necessary to migrate to Opensearch.

MOOG-17473: The Moogsoft AIOps Grafana plugin v8.0.2 is published

MOOG-17470: Upgraded RabbitMQ to v3.9.13 & Erlang to v23.3.4.11

MOOG-17463: alertDelta/situationDelta WFE actions now utilise a new BotUtility function named "hasNullParent" to identify if an element which currently exists in the event/alert/situation object does not have a parent in the ‘previousData’ data block.

MOOG-17460: The splitter no longer makes use of timestamps stored in the split_last_timestamp table to set a lower bounds for its alert/situation selection queries. Additionally the moog_farmd log line “Running Data Splitter on all data [from <timestamp>]” is no longer applicable and has been removed

MOOG-17447: Log4j has been upgraded to version 2.17 and Opensearch v1.2.4 swapped in to combat recent vulnerabilities in log4j.

MOOG-17441: The archiver now uses fixed timestamps for its batch queries rather than relative which, in turn, prevents scope issues.

MOOG-17436: The HAProxy server/client timeouts, as deployed by the ha_proxy_installer script, have been increased to the maximum allowed values (24d).

MOOG-17409: Made MTTA/MTTD widgets' alias inline with endpoints preserving alphabetical order on global dashboard
