How to delete old data in prometheus

[瞿谷歌]

I execute the api request as follow：

/api/v1/admin/tsdb/delete_series?match[]={job="xxx"}

and

/api/v1/admin/tsdb/clean_tombstones

but when i execute the query by "/api/v1/query" ,the data what should be deleted is still returned.

Can you give some suggestion?

Hello 瞿谷歌,

Per the documentation - this sequence of steps should indeed delete your series. This sounds like unexpected behaviour so I would suggest raising an issue against the Prometheus Github repository and provide as much relevant information as you can.

Best,

Ian

You didn't say exactly how you submitted the request, but if you are using curl, then use the -g flag to stop it doing its own globbing.  You'll also need to quote the whole lot to stop the shell messing with it too.
