Hi @lijom200,
Hmm, if you have designed the pattern parser and only need to trim out the other details e.g. timestamp but only up to seconds,
Then you can use Functions e.g. Overwrite OR Transformations inside the Panel. Here is a small screencast of how I converted the timestamp using Overwrite:
Also, another alternative is to define the settings in the grafana.ini configuration as shown in this post.
I hope I answer your question
