What this PR does:
I propose to increased
CortexIngesterReachingSeriesLimitwarning threshold from 70% to 80% and critical threshold from 85% to 90%.Reason is to try to reduce a bit the noise from this alert. With an organic grow of series, it takes time to do a 10% jump, so even a 10% room once the critical alert is fired should be enough to address it. On the other side, if we get a sudden jump (eg. because of a misconfiguration) we'll not have time to address it before the limit is hit anyway (so we'll hit the limit, get paged and then we'll address it).
Which issue(s) this PR fixes:
