Using Fm API V2 allows the collectd plugins to distinguish between FM connection failures and no existing alarm query requests on process startup as well as failure to clear or assert alarms during runtime so that such actions can be retried on next audit interval. This allows the plugins to be more robust in its alarm management and avoids leaving stuck alarms which fixes the following three reported stuck alarm bugs. Closes-Bug: https://bugs.launchpad.net/starlingx/+bug/1802535 Closes-Bug: https://bugs.launchpad.net/starlingx/+bug/1813974 Closes-Bug: https://bugs.launchpad.net/starlingx/+bug/1814944 Additional improvements were made to each plugin to handle failure paths better with the V2 API. Additional changes made by this update include: 1. fixed stale unmounted filesystems alarm handling 2. percent usage alarm actual readings are updated on change 3. fix of threshold values 4. add 2 decimal point resolution to % usage alarm text 5. added commented FIT code to mem, cpu and df plugins 6. reversed True/False return polarity in interface plugin functions Test Plan: Regression: PASS: normal alarm handling with FM V2 API ; process startup PASS: normal alarm handling with FM V2 API ; runtime alarm assert PASS: normal alarm handling with FM V2 API ; runtime alarm clear PASS: Verify alarms of unmounted fs gets automatically cleared PASS: Verify interface alarm/clear operation Robustness: PASS: Verify general startup behavior of all plugins while FM is not running only to see it start at some later time. PASS: Verify alarm handling over process startup with existing cpu alarms while FM not running. PASS: Verify alarm handling over process startup with existing mem alarms while FM not running. PASS: Verify alarm handling over process startup with existing df alarms while FM not running. PASS: Verify runtime cpu plugin alarm assertion retry handling PASS: Verify runtime cpu plugin alarm clear retry handling PASS: Verify runtime cpu plugin handling over process restart PASS: Verify alarm handling over process startup with existing cpu alarms while FM initially not running and then started. PASS: Verify runtime mem plugin alarm assertion retry handling PASS: Verify runtime mem plugin alarm clear retry handling PASS: Verify runtime mem plugin handling over process restart PASS: Verify alarm handling over process startup with existing mem alarms while FM initially not running and then started. PASS: Verify runtime df plugin alarm assertion retry handling PASS: Verify runtime df plugin alarm clear retry handling PASS: Verify runtime df plugin handling over process restart PASS: Verify alarm handling over process startup with existing df alarms while FM initially not running and then started. PASS: Verify alarm set/clear threshold boundaries for cpu plugin PASS: Verify alarm set/clear threshold boundaries for memory plugin PASS: Verify alarm set/clear threshold boundaries for df plugin New Features: ... threshold exceeded ; threshold 80.00%, actual 80.33% PASS: Verify percent usage alarms are refreshed with current value PASS: Verify percent usage alarms show two decimal points Change-Id: Ibe173617d11c17bdc4b41115e25bd8c18b49807e Signed-off-by: Eric MacDonald <eric.macdonald@windriver.com> |
