Overview
This charm provides OpenStack service checks for Nagios
Usage
juju deploy cs:~canonical-bootstack/openstack-service-checks
juju add-relation openstack-service-checks nrpe
This charm supports relating to keystone via the keystone-credentials interface. If you do not wish to use this, you can supply your own credential set for Openstack by adding 'os-credentials' setting (see setting description hints)
juju config openstack-services-checks os-credentials=" ... "
With Keystone
juju add-relation openstack-service-checks:identity-credentials keystone:identity-credentials
API endpoints monitoring
If your OpenStack API endpoints have a common URL for the Admin, Public and Internal addresses, you should consider disabling some endpoints which would be duplicated otherwise, e.g.
juju config openstack-service-checks check_internal_urls=False check_admin_urls=False
If such API endpoints use TLS, new checks will monitor the certificates expiration time:
juju config openstack-service-checks tls_warn_days=30 tls_crit_days=14
Note: in order to have endpoint checks updated on endpoint changes you should also relate identity-notifications:
juju add-relation keystone:identity-notifications openstack-service-checks:identity-notifications
Alternatively, instead of the above relation, there is also an action "refresh-endpoint-checks" available. Running this action will update the service checks with the current endpoints.
Octavia Checks
Knowning when an openstack load-balancer is having an issue is an important operational situation which this charm helps manage. There is both course grain control over octavia checks, as well as more fine-grained control by use of the following config items.
Course Grain
check-octavia:trueorfalsecan enable or disable checks
Fine Grain
octavia-loadbalancers-ignoredoctavia-amphorae-ignoredoctavia-pools-ignoredoctavia-image-ignored
Each of these config items adds an ignore-list of keywords. Each keyword in the ignore list will be blocked when it appears in the output of the check.
Examples
Ignoring a test or non-production loadbalancer with the ID=deadbeef-1234
-56789012-dead-beef which is INACTIVE or DEGRADED.
juju config my-openstack-service-checks octavia-loadbalancer-ignored='deadbeef-1234-56789012-dead-beef,'
Ignoring all loadbalancers which happen to be DEGRADED.
juju config my-openstack-service-checks octavia-loadbalancer-ignored='DEGRADED,'
Ignoring amphorae that are stuck in BOOTING state
juju config my-openstack-service-checks octavia-amphorae-ignored='BOOTING,'
Masakari Checks
Alert when the openstack compute nodes protected by Masakari are on maintenance during a failure. Follow-up must be done to re-enable the service for nodes marked by Masakari as being in maintenance state.
juju config openstack-service-checks check-masakari=true
Compute services monitoring
Compute services are monitored via the 'os-services' interface. Several thresholds can be adjusted to tweak the alerting system: number of available nodes per host (warning and critical thresholds), ignore certain host aggregates (by default, no aggregates are skipped), ignore nodes in 'disabled' state.
juju config openstack-service-checks nova_warn=2 nova_crit=1
juju config openstack-service-checks skipped_host_aggregates='hostaggr1,hostaggr2'
juju config openstack-service-checks skip-disabled=true
Rally checks
A new nrpe check supports a limited list of rally/tempest tests, which can be scheduled to run via cron (default cronjob schedule is every 15 minutes). Tests can also be skipped as follows (available components are cinder, glance, nova and neutron):
juju config openstack-service-checks check-rally=true
juju config openstack-service-checks rally-cron-schedule='*/20 * * * *'
juju config openstack-service-checks skip-rally='nova,neutron'
