Updating logstash filters
Sadly, there is no programmatic access to Logit’s logstash filters.
For new logit stacks…
If the logit stack is not a v6.x logstash (e.g. it’s a v5.6 like the current PaaS stacks are)
the new filters need a plugin installed into logstash. You need to request this via logit support
(either through the web-based “chat” logit have once you’ve logged in or via their email address).
The plugin is for a filter called
alter. v6.x logstash logit stacks have this plugin
installed by default. Such a request might look like:
Please could you install the “alter” filter plugin into logstash for the stack with id e3352477-f40c-41c5-be46-5c52c0e3de38?
Process for generating logstash filters for Logit
We have instead come up with the following method.
- Create your branch on PaaS-CF.
- Make your changes and commit them as usual.
- Two “upstream” repositories are used to generate the filter configuration. The required tags within each repository are specified in the Makefile (see the
logit-filterstarget) - update them if required.
make logit-filtersfrom the paas-cf directory (requires docker). This updates the
config/logit/output/generated_logit_filters.conffile with the latest filter configuraton.
- Check the diff for any potential gotchas.
- Log into logit via Google[external link].
- From the dashboard view, select the Settings button for the stack you wish to modify.
- Select Logstash Filters and wait for the current page to load.
- Select all of the existing filters and delete them.
- Paste in your new filters and select Validate.
- If the validation passes an Apply button will appear. Select this button.
- Wait for application of the filters to finish.
