new metrics:

    1. drbd metric local disk resource monitoring (#26)
ha_cluster_drbd_resource{disk_state="uptodate",resource_name="1-single-0",role="Secondary",volume="0"} 1
ha_cluster_drbd_resource{disk_state="uptodate",resource_name="1-single-1",role="Secondary",volume="0"} 1
ha_cluster_drbd_resource{disk_state="uptodate",resource_name="vg1",role="Secondary",volume="0"} 1
ha_cluster_drbd_resource{disk_state="uptodate",resource_name="vg2",role="Secondary",volume="0"} 1
ha_cluster_drbd_resource{disk_state="uptodate",resource_name="vg3",role="Secondary",volume="0"} 1
    1. Monitor remote DRBD disk resource
ha_cluster_drbd_resources_remote_connection{peer_disk_state="dunknown",peer_node_id="0",peer_role="Unknown",resource_name="drbd_passive",volume="0"} 1

Improvements:

  • pacemaker metrics refactored in separated file and implemented unit-tests (#45)

  • introduced level logging (#48)

  • introduced wrapping errors(#48)

  • handle error better: don't panic, just skip metric and print error in logs. (#23)
