Thread: pgBadger: Cannot find any log entries from systemd-journald

Hello,

I think I just might did a small configuration issue, but somehow I cannot figure it out by myself.

I want to let pgbadger directly fetch data from journald -- so I was using with a unexpected outcome:

$ pgbadger --journalctl "journalctl -u postgresql.service"
LOG: Ok, generating html report...s: 0, events: 0

Having a look into the journal there is a lot of

My psotgresql.conf looks like:

log_autovacuum_min_duration = 0
log_checkpoints = yes
log_connections = yes
log_destination = 'stderr'
log_disconnections = yes
log_error_verbosity = 'verbose'
log_line_prefix = '%t [%p]: user=%u,db=%d,app=%a,client=%h '
log_lock_waits = yes
log_min_duration_statement = 100
log_temp_files = 0
---cut----

Any idea what I missed or did wrong?

Cheers,
Frank

Try as root? Or is pgbadger a setuid program?

No difference. The user executed under is having also rights to see the journal.

No, unfortunately not. Though, it adds some more nice information in general, but none that actually helped me.

It was just an random pick to show there is a bunch of logging -- I also can see checkpoints and vacuum etc. I just
didn'twant to paste 1GB of log ;)
 

You can get an idea of what is actually parsed by running "journalctl -u postgresql --output=short-iso"

Looks good to me.

I tried to change it, but in my case no difference.
