When launching the console or when I created a new tab it got stuck for about 5-10 seconds before I got my prompt.

If you are like me and are spending most of your time in Terminal.app you understand how annoying this is/was.

I tried to rename .profile, .inputrc and evey other startup script I had in my home folder but the problem did not go away.

Then I found an OSX user which had his Terminal crash when started. He solved his problem by cleaning up some OSX systemlogs. So I thought I try the same trick.

The logfiles which he removed where the asl files under /private/var/log/asl/

I read about them here: http://macosx.com/tech-support/can-i-deleteasl-log/24223.html

But I figured I’d just remove them all :)

1
sudo rm -rf /private/var/log/asl/*

When all asl files where removed my Terminal went back to normal again and I am sooooooo relieved.

This worked for me BUT I do not recommend you to remove anything if you do not know what you are doing!!!

Cheers!

On the machine syslog-ng where installed as logging daemon and I have never worked with PostgreSQL logging and syslog-ng. This post is about how to get them to work together.

pgFouine is pretty simple to setup and the process is where well documented at their website (http://pgfouine.projects.postgresql.org/tutorial.html).

However syslog-ng is very different if you are used to “normal” syslog daemon.

The first thing you have to do is setup PostgreSQL as the instructions says on the website. The next step is to tell syslog-ng to log you postgres data to a separate file.

The first thing to create in syslog-ng.conf is a destination. Destination blocks is used to send logs somewhere.

By adding the following row we tell syslog-ng that there is a destination called postgres and that we want this data in /var/log/pgsql.

1
destination postgres { file("/var/log/pgsql"); };

Now we are ready to add a filter to caputre our PostgreSQL data. Filters can both be used to include or exclude data from you logs. The following row in your syslog-conf captures all data sent to local0 or whatever you called it in postgresql.conf :-)

1
filter f_postgres { facility(local0); };

It’s time to join our destination with our filter and the following line tells syslog-ng to join our source, destination and filter together.

1
log { source(src); filter(f_postgres); destination(postgres); };

Put these lines in your syslog-ng.conf and restart syslog-ng and also PostgreSQL and you will have logging in a separate file!

Next step is to write a little guide to pgFouine ;)

Cheers!
