Bug Report

What did you do?
Someone sent a large query such as {__name__=~".+"}[5d] to our prometheus host.

What did you expect to see?
I expect the query to timeout before completing, while consuming some memory and CPU along the way.

What did you see instead? Under which circumstances?
The query runs until it exhausts all available memory on the host and OOM killer get is. I have set it up in a repro env locally and the query has been running for ~60m (its still going) even though I have the timeout set to the default 2m.

Environment

  • Prometheus version:

2.2

Same symptoms as #4288

This doesn't sound right, it shouldn't take 2m just to lookup the index. How many time series do you have? Can you share your config?

My prod hosts have >10MM timeseries per box (don't see a metric for it besides a count in head, which is the lower bound). I'm not sure how many this test host has, as itI'm not the only reporter of this issue (#4290) FWIW.

So let's say you had 10MM series, with 2h blocks you'd then be doing 10MM*(24/2)*5 = 600MM series lookups, and using a regex matcher. Doesn't sound too surprising to me that that could take >2m. Unless each series lookup is <.2 microseconds.

Return whatever data is available when there is a failed remote read 
Signed-off-by: Mark Knapp <mknapp@hudson-trading.com>

Bubble up errors to promql from populating iterators (prometheus#4136)

This changes the Walk/Inspect API inside the promql package to bubble
up errors. This is done by having the inspector return an error (instead
of a bool) and then bubbling that up in the Walk. This way if any error
is encountered in the Walk() the walk will stop and return the error.
This avoids issues where errors from the Querier where being ignored
(causing incorrect promql evaluation).

This changes the Walk/Inspect API inside the promql package to bubble
up errors. This is done by having the inspector return an error (instead
of a bool) and then bubbling that up in the Walk. This way if any error
is encountered in the Walk() the walk will stop and return the error.
This avoids issues where errors from the Querier where being ignored
(causing incorrect promql evaluation).

* Reorder startup and shutdown to prevent panics. (prometheus#4321)

Start rule manager only after tsdb and config is loaded.
Stop rule manager before tsdb to avoid writing to closed storage.
Wait for any in-progress reloads to complete before shutting
down rule manager, so that rule manager doesn't get updated after
being shut down.

Remove incorrect comment around shutting down query enginge.
Log when config reload is completed.
