James Peach resolved TS-2931. ----------------------------- Resolution: Fixed > plugin metrics fail after a crash > --------------------------------- > > Key: TS-2931 > URL: https://issues.apache.org/jira/browse/TS-2931 > Project: Traffic Server > Issue Type: Bug > Components: Plugins, TS API > Reporter: James Peach > Assignee: James Peach > Fix For: 5.1.0 > > > If a plugin uses {{TSStatFindName}} followed by {{TSStatCreate}}, > {{TSStatFindName}} can return 0 for all the metric IDs after a > {{traffic_server}} crash. > AFAICT this will happen every time with the following conditions: > 1. traffic_manager has pulled the plugin stat records from traffic_server > 2. traffic_server crashes > When traffic_server comes back up, it pulls the records from traffic_manager. > traffic_manager sends the records including the rsb_id field. However, > RecForceInsert() does not copy the rsb_id field from the message to the > actual record. There are 2 reasonable fixes: > - We could not propagate the 'registered' flag for records that we on. This > forces the code to re-register, which will bring the stats back to the > correct state. > - We could ensure that we copy the rsb_id field so that stat lookups succeed. -- This message was sent by Atlassian JIRA (v6.2#6252)
