Tobias Klausmann	b998636893	Improve error logging for missing config and QL dir (#10260 ) * Improve error logging for missing config and QL dir Currently, when Prometheus can't open its config file or the query logging dir under the data dir, it only logs what it has been given default or commandline/config. Depending on the environment this can be less than helpful, since the working directory may be unclear to the user. I have specifically kept the existing error messages as intact as possible to a) still log the parameter as given and b) cause as little disruption for log-parsers/-analyzers as possible. So in case of the config file or the data dir being non-absolute paths, I use os.GetWd to find the working dir and assemble an absolute path for error logging purposes. If GetWd fails, we just log "unknown", as recovering from an error there would be very complex measure, likely not worth the code/effort. Example errors: ``` $ ./prometheus ts=2022-02-06T16:00:53.034Z caller=main.go:445 level=error msg="Error loading config (--config.file=prometheus.yml)" fullpath=/home/klausman/src/prometheus/prometheus.yml err="open prometheus.yml: no such file or directory" $ touch prometheus.yml $ ./prometheus [...] ts=2022-02-06T16:01:00.992Z caller=query_logger.go:99 level=error component=activeQueryTracker msg="Error opening query log file" file=data/queries.active fullpath=/home/klausman/src/prometheus/data/queries.active err="open data/queries.active: permission denied" panic: Unable to create mmap-ed active query log [...] $ ``` Signed-off-by: Tobias Klausmann <klausman@schwarzvogel.de> * Replace our own logic with just using filepath.Abs() Signed-off-by: Tobias Klausmann <klausman@schwarzvogel.de> * Further simplification Signed-off-by: Tobias Klausmann <klausman@schwarzvogel.de> * Review edits Signed-off-by: Tobias Klausmann <klausman@schwarzvogel.de> * Review edits Signed-off-by: Tobias Klausmann <klausman@schwarzvogel.de> * Review edits Signed-off-by: Tobias Klausmann <klausman@schwarzvogel.de>	3 years ago

Julien Pivotto	9adad8ad30	Remove MaxConcurrent from the PromQL engine opts (#6712 ) Since we use ActiveQueryTracker to check for concurrency in `d992c36b3a` it does not make sense to keep the MaxConcurrent value as an option of the PromQL engine. This pull request removes it from the PromQL engine options, sets the max concurrent metric to -1 if there is no active query tracker, and use the value of the active query tracker otherwise. It removes dead code and also will inform people who import the promql package that we made that change, as it breaks the EngineOpts struct.

By moving all atomically accessed variables to the beginning of the struct they are guaranteed to be 64 bit aligned.

Advait Bhatwadekar	5d401f1e1b	Added query logging for prometheus. Issue #1315 (#5794 ) * Added query logging for prometheus. Options added: 1) active.queries.filepath: Filename where queries will be recorded 2) active.queries.filesize: Size of the file where queries will be recorded. Functionality added: All active queries are now logged in a file. If prometheus crashes unexpectedly, these queries are also printed out on stdout in the rerun. Queries are written concurrently to an mmaped file, and removed once they are done. Their positions in the file are reused. They are written in json format. However, due to dynamic nature of application, the json has an extra comma after the last query, and is missing an ending ']'. There may also null bytes in the tail of file.
