- add new metrics (off by default)
- add Debug boolean option for full metric details
- add Timezone option for 'running_since' field
- update default metrics shown and their constants
- remove utils.GetStartTime(), now use process metrics
CPU profiling changes:
cgr-engine.go:
- use filepath.Join instead of path.Join
- handle *CoreService.StopCPUProfiling error inside deferred function
- same with the error from *os.File.Close()
cores/core.go:
- StartCPUProfile now returns an *os.File (as opposed to an io.WriteCloser),
because os.File.Stat is used beforehand to check if a handler of the file is
already active and confirm the status of profiling. Asserting the type would
have worked as well.
- handle pprof.StartCPUProfile error and ensure file is closed before returning
- log file close error as a warning if it occurs
- return missing mandatory error with correct path field name ('DirPath')
- no need to check if fileCPU is nil for profiling status
- pprof.StartCPUProfiling will return an error if profiling is already started
- os.File.Close() will return ErrClosed if profiling is already stopped
- differentiate between calling StopCPUProfiling when profiling hasn't started
and when it was already stopped by returning appropriate errors
Memory profiling changes:
- merge StopChanMemProf with StopMemoryProfiling
- remove fileMEM and stopMemProf from struct and constructors
- add separate mutex for memory profiling, ensure thread safety
- handle all significant errors
- log error if StopMemoryProfiling fails during CoreS Shutdown
- ignore errors if profiling inactive in Shutdown and deferred Stop
- move validations inside V1 functions
- return error if StartMemoryProfiling already started
- return error if StopMemoryProfiling already stopped or never started
- close profiling loop on error, not the cgr-engine
- StopMemoryProfiling closes channel and profiling loop writes final profile
- rename Path to DirPath for mandatory field error
- rename memprof_nrfiles flag to memprof_maxfiles
- increase default memprof_interval
- consider MaxFiles <= 0 as unlimited
- move memory profiling logic after starting services
- use CoreService Start/StopMemoryProfiling in main
- remove final memory profile block (created by deferred Stop)
- convert MemProfiling to method on CoreService and rename to profileMemory
- use Ticker for recurrent actions instead of Timer
- compute mem_final.prof full path in StartMemoryProfiling
- suffix profile files with current time instead of numbers
- update dispatcher methods after changes
- move MemoryPrf from utils to cores, rename to MemoryProfilingParams
- add logs for starting/stopping profiling
- added the possibility to disable timestamps in the memory profile file names
and use increments of 1 instead.
Other changes:
- improved integration tests for flags (now table tests)
- improved profiling integration tests
- renamed parameter type: ArgsReplyFailedPosts -> ReplayEventsParams
- renamed param fields:
- FailedRequestsInDir -> SourcePath
- FailedRequestsOutDir -> FailedPath
- TypeProvider -> Provider
- changed param fields types from *string to string
- used the SourcePath and FailedPath params directly instead of creating separate variables
- used filepath.WalkDir instead of reading the directory and looping over the entries
- used slices.ContainsFunc to check if the file belongs to any module (if 1+ is specified)
- used filepath.Join instead of path.Join
- used the path provided by WalkFunc instead of building the file paths ourselves
- made error returns more descriptive
- added logs for directories/files that are skipped
- paths that cannot be accessed are skipped after logging the error
Git 2.45+ introduced a backward incompatible change in the iso-strict
date format, showing time in the Zulu timezone with Z suffix instead
of +00:00. This commit adds parsing for the new date format before
falling back to the old format.
Revise GetCGRVersion error messages.
Revise GetCGRVersion unit test.
HierarchyPath parser now returns nil when
the path is empty (instead of a string slice with one
EmptyString element).
If isAbsolute is set to true, when calling the AsString
method on a nil HierarchyPath, only the separator will
be returned. Alternatively, if isAbsolute is false, it
will just return . to signal that the path currently
being processed is the one required.This avoids a nil
expr error coming from the xmlquery library.
Use the Query and QueryAll functions from the xmlquery
package to be able to handle the errors ourselves and
avoid panics.
Remove config default value for xmlRootPath. The field
will remain commented in config_defaults for reference.
Add tests for HierarchyPath.AsString function.
Add comments for XmlProvider and xmlRootPath opt.
Update XmlProvider String() func based on the comment
which specifies that it should display the already
parsed values out of cache.
