The openstack-infra team has put a lot of effort into creating logstash
filters to parse openstack logs. These filters are primarily used to
parse service logs from devstack runs, but should work for production
deployments as well. Yesterday I worked with Clark Boylan to move these
filters out of puppet and into their own project called
openstack-infra/logstash-filters to make them easy to reconsume. This
project has three files in the filters/ directory: an example input
section, an example output section, and the filters section used to
index devstack service log data into logstash.openstack.org. Using
conf.d style logstash configs, you can easily drop these filters into
your own config while using custom input and output config sections. You
can see how this is done for logstash.openstack.org using puppet at .
These filters work by switching on tags for the different log formats.
In order for them to parse the logs correctly, the correct tags need to
be applied to the logs before they reach the filters. The tags applied
to the devstack service logs can be viewed at . Most service logs use
the "oslofmt" tag, but some require the "apachecombined" tag instead.
The filters also understand the "libvirt" and "syslog" tags for their
respective standard log formats.
