Aliaksandr Valialkin	88c2631320	lib/protoparser: remove superflowous memory allocations during protocol parsing	2022-04-06 14:00:50 +03:00
Nikolay	dd53abf36d	changes protoparser apis for accepting reading from io.Reader (#1624) ... adds InsertHandlerForReader apis to vmagent	2021-09-20 14:54:20 +03:00
Aliaksandr Valialkin	ebaf68bcb0	lib/protoparser: stop reading the input stream as soon as the callback provided by the caller returns error ... This is a follow-up for af90c3c43b	2021-06-14 15:20:38 +03:00
Aliaksandr Valialkin	e2717d84c0	all: various fixes in command-line flag descriptions	2021-03-15 22:03:49 +02:00
Aliaksandr Valialkin	1a237c6903	all: properly handle CPU limits set on the host system/container ... This can reduce memory usage on systems with enabled CPU limits. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/946	2020-12-08 21:07:03 +02:00
Aliaksandr Valialkin	22c1e29284	lib/protoparser: propagate callback error to the caller of ParseStream for every supported data ingestion protocols ... The caller of ParseStream then can generate HTTP 503 responses for non-nil errors occured in callbacks when processing incoming requests. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/896	2020-11-13 13:05:34 +02:00
Aliaksandr Valialkin	ed724d25ba	lib/promscrape: add stream parse mode for efficient scraping of targets that expose millions of metrics	2020-11-01 23:12:26 +02:00
Aliaksandr Valialkin	1481d6d8ff	lib/protoparser: avoid copying of buffer read from the network to unmarshal buffer	2020-09-28 17:19:04 +03:00
Aliaksandr Valialkin	8df33bd5c1	app/{vminsert,vmagent}: improve data ingestion speed over a single connection ... Process data obtianed from a single connection on all the available CPU cores.	2020-09-28 04:14:51 +03:00
Aliaksandr Valialkin	7072db75cb	lib/protoparser: use 64KB read buffer instead of default 4KB buffer provided by net/http.Server ... This should reduce syscall overhead when reading big amounts of data	2020-09-28 02:07:19 +03:00
Aliaksandr Valialkin	00ec2b7189	lib/protoparser: use all the available CPU cores for processing ingested data from a single /api/v1/import stream ... Previously a single data ingestion stream to /api/v1/import could load only a single CPU core.	2020-09-26 04:22:06 +03:00
Aliaksandr Valialkin	6aab2f4989	all: allow using KB, MB, GB, KiB, MiB and GiB suffixes in command-line flag values related to byte sizes or byte rates	2020-08-16 17:08:28 +03:00
Aliaksandr Valialkin	2012e294d1	properly calculate readCalls	2020-07-10 12:01:05 +03:00
Aliaksandr Valialkin	d962568e93	all: use %w instead of %s for wrapping errors in fmt.Errorf ... This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode . See https://blog.golang.org/go1.13-errors for details.	2020-06-30 23:33:46 +03:00
Aliaksandr Valialkin	6a1aab88fd	lib/protoparser: metrics renaming: vm_protoparser_<type>_* -> vm_protoparser_*{type="<type>"} ... This should improve composability of these metrics in PromQL queries	2020-02-28 20:19:59 +02:00
