MAS-HTTP-LRQ Exporter

Maximo-CPI offers several Prometheus exporters, including the MAS-HTTP-LRQ Exporter. This exporter is used to collect metrics related to HTTP requests, slow calls, and long-running queries for both MAS Core and Manage app.

Warning: This exporter leverages logging and custom metric collection features, and is only supported when maximo-cpi is deployed on the OpenShift cluster.

Below are the scripts/command to enable and disable the exporter:

  • mas-http-lrq-exporter-enable.sh <manage namespace name> to enable the exporter.
  • mas-http-lrq-exporter-disable.sh <manage namespace name> to disable the exporter.

Notes:

  • The exporter supports multi-instances on the same cluster

  • The enable script:

    • create scripts mas-<instance>-core-exporter, mas-<instance>-manage-exporter, mas-<instance>-manage-lrq-exporter under /opt/app-root/src/server/metricscript
    • create and apply podmonitors for mas-<instance>-core-exporter, mas-<instance>-manage-exporter, mas-<instance>-manage-lrq-exporter in the cluster
    • enable manage long running query
    • update /etc/rsyslog.conf for the logging collection
    • build <instance>-stats-cron under /etc/cron.daily for log archive and rotation. By default, RSYSLOG_RETENTION_DAYS is set to 7. You can adjust the value by setting an environment variable like export RSYSLOG_RETENTION_DAYS=7

  • The disable script removes all the above scripts except the configuration in /etc/rsyslog.conf.
