is it possible to remove all labels of a metrics in a program?

[godsarmy]

Hi

I know it is possible delete a data with label for internal metrics like 'del metrics[$label]'. But is it possible to have a quick way to remove all the labels in a metrics immediately?

I have a scenario to count differnt item's' current value in a metrics but the system could be reset (generate some reset string pattern in log) so that i would like to reset all data in the metrics in this case.

I do not think "del metrics after" could help me because the metrics should not expire until reset. Also the lablel name is not determined. So i do not have explict label names to delete.

For metrics without label, i can reset metrics value to zero to work around reset. But i do not have a way to handle metrics with labels.. The ony method in my mind is to restart mtail.

There is not such a way. Only restarting the mail process will reset the variable store.

If mtail is restarted, it doesn't restore any state; it loads the programs and creates brand new metrics, then starts reading the log files at the current end of file position. So any metrics created are from a "clean slate".

Right now in #617 I'm implementing a size limit for metrics, though; can you take a look at that bug and see if it suits your needs instead?

But even if mtail restarted, it would still read logs before reset status to import as metrics. If we can not handle labels individually, is it possible to add a feature to reset mtail into clean slate status when matching a pattern in log?
