Not really enough users/crash data from the 3.6b1 release last week to tell where we are with crash fixing for 3.6. Still under 2000 crashes per day and only 601 signatures to look at. That's around the same that 3.5.x releases get during during their pre-release period.

Breakpad & Socorro

    • metrics goals and priorities and high level goals
    • storage situation and retention policies
      • raw crash dumps/jsons (used as deferred storage)
        • 7 Days (no backups) - currently stored on a freebsd NAS server - disks are redundant, hardware not redundant.
      • storage of processed crash dumps and jsons (processed)
        • The jsons will be stored for 3 years (haven't deleted any yet) - Currently stored on a sun thumper, disks are redundant, hardware not redundant. Not being backed up currently, but we have a bug in place to back these up (should be done something in the next couple of weeks).
        • The processed raw dumps are on the same freebsd NAS as above. My current plan is to wipe them out after a week.
      • disk space for the database server
        • Currently on equallogic storage arrays.
        • The head is not redundant, but the disk is redundant.
        • This is backed up onto another eql storage volume every night, and WAL is played back on the backup server to keep things current. (not dumped to tape).
      • other storage?
    • Future Storage - two minutes talking about the hadoop/hdfs plan
    • socorro roadmap
