Yep, however pmdapostgres already has support for a number of different versions of postgres. Mostly its variants of the 9.x series though - we'll need some logic to deal with missing postgres functionality to fix this... > -DATE: postgresql.stat.sys_tables.idx_tup_fetch: OK > -DATE: postgresql.stat.xact.all_tables.seq_scan: OK > -DATE: postgresql.stat.xact.sys_tables.idx_scan: OK > +DATE: postgresql.stat.sys_tables.idx_tup_fetch: BAD > +DATE: postgresql.stat.xact.all_tables.seq_scan: BAD > +DATE: postgresql.stat.xact.sys_tables.idx_scan: BAD > DATE: postgresql.statio.sys_indexes.idx_blks_hit: OK > -DATE: postgresql.statio.sys_tables.idx_blks_read: OK > +DATE: postgresql.statio.sys_tables.idx_blks_read: BAD Ah, lots of clues there. > +cat: /tmp/778-27579.nomatch: No such file or directory (looks like an unexpected code path in qa/778 - just fixed upstream) > .. so I guess pmda works after all. Yep - so, I'm inclined to defer this bug for now, seems not so critical for this stage of 6.8 life-cycle. > Also, some errors - among a huge pile of warnings and others - were logged > in pmcd/postgresql.log: > > DBD::Pg::st execute failed: ERROR: function pg_is_in_recovery() does not > exist > DBD::Pg::st execute failed: ERROR: function pg_is_in_recovery() does not > exist Ah, OK - the recovery metrics need to be made version-conditional. > [Tue Feb 2 16:49:57] pmdapostgresql(5646) Error: pmdaFetch: Fetch callback > error from metric PMID 110.7.0[-1]: Missing metric value(s) 110.7.* is the postgresql.active.* metrics. > error from metric PMID 110.8.3[-1]: Missing metric value(s) > [Tue Feb 2 16:49:57] pmdapostgresql(5646) Error: pmdaFetch: Fetch callback 110.8.* is the postgresql.recovery.* metrics. > DBD::Pg::st execute failed: ERROR: function pg_is_in_recovery() does not > exist > DBD::Pg::st execute failed: ERROR: function pg_is_in_recovery() does not > exist So all of the above messages are because this older version of postgres doesn't support the recovery functionality. > There's also a similar bug reported against RHEL7, > https://bugzilla.redhat.com/show_bug.cgi?id=1252322, but that one is much > more silent. Yep, similar, but different (postgres versions) again. Upstream commits 85cc4f2586bc and a076c50634a8 tackle this. Verified with build pcp-3.10.9-8.el6.
