we would like to do the following:

- monitor an application logfile for a pattern match
- if/when there's a pattern match, trigger/run a script or command


thanks

Do you mean event log or file log?

this would be our own or a 3rd-party file log - not windows event logs.

Then you should read about using the File trigger. The problem is, from what I understand, that you want to watch the content of the file you are watching? Is that right?

You can always track that changes has been made to that file but the problem is that you need to reload the file, as it is constructed right now. If the file is big and you have a lot of changes this may not be efficient.

I think you are requesting some kind of tail function with matching in it?

yes indeed, i believe your last statement (tail function with pattern match) sums it up...

We need to investigate more about this. How this can be solved the best way. I am moving this topic to Feature requests.

This would be an extremely nice feature.

We currently use another tool that performs this function. I found that it is possible to create a monitor in that tool, and then schedule and run it from VisualCron as an http command - a condition is used to check the output for the result that would result in VC taking some action on it.

It would be much nicer to have this integrated into VC, and based on a trigger, rather than frequently scheduled checks.
