Thread: Moving from pgFouine to pgBadger Issue with Total query duration metric
Hi,
It could be a case of pgFouine not picking up/reporting all the queries when it calculates those stats. I see all the metrics matching closely in either reports except for the total query duration and query peak times. pgFouine thinks that there has been a peak of 6 queries/second at 2018-01-11 14:26:18 while pgBadger thinks there has been a peak of 6 queries/second at 2018-01-11 17:41:30, which could be right but it may be a different set of queries.

Subject: Moving from pgFouine to pgBadger Issue with Total query duration metric
Hi ,
I am moving from pgFouine to pgBadger. When I compare the reports I see that there is major difference in time reported by metric Total query duration for given same postgres server log file.( excuse me for not sharing the postgres server logfile )
pgfouine reports around 2hrs where as pgBadger reports around 4hrs.
I am using below command options to execute the report. I am mainly comparing pgBadger report with queries.html report
Appreciate your help on this ? wanted to know why there so much difference in time ?
pgFouine
/home/postgres/fouine/pgfouine-1.2/pgfouine.php -logtype stderr -file $filename -top 30 \
-report /tmp/queries.html=overall,bytype,slowest,n-mosttime,n-mostfrequent,n-slowestaverage \
-report /tmp/hourly.html=overall,hourly \
-report /tmp/errors.html=overall,n-mostfrequenterrors \
-database $1
pgBadger
perl pgbadger -t 30 --disable-session --disable-connection --disable-lock --disable-temporary --disable-checkpoint --disable-autovacuum -o pgbadger_out_3.html -d <DBNAME> /home/postgres/postgresql-2018-01-11_000000.log
