Configure an HTTP endpoint for metrics
editConfigure an HTTP endpoint for metrics
editThis functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
Journalbeat can expose internal metrics through an HTTP endpoint. These are useful to monitor the internal state of the Beat. For security reasons the endpoint is disabled by default, as you may want to avoid exposing this info.
The HTTP endpoint has the following configuration settings:
-
http.enabled
-
(Optional) Enable the HTTP endpoint. Default is
false
. -
http.host
-
(Optional) Bind to this hostname, IP address, unix socket (unix:///var/run/journalbeat.sock) or Windows named pipe (npipe:///journalbeat).
It is recommended to use only localhost. Default is
localhost
-
http.port
-
(Optional) Port on which the HTTP endpoint will bind. Default is
5066
. -
http.named_pipe.user
- (Optional) User to use to create the named pipe, only work on Windows, Default to the current user.
-
http.named_pipe.security_descriptor
- (Optional) Windows Security descriptor string defined in the SDDL format. Default to read and write permission for the current user.
This is the list of paths you can access. For pretty JSON output append ?pretty
to the URL.
You can query a unix socket using the cURL
command and the --unix-socket
flag.
curl -XGET --unix-socket '/var/run/{beatname_lc}.sock' 'http:/stats/?pretty'
Info
edit/
provides basic info from the Journalbeat. Example:
curl -XGET 'localhost:5066/?pretty'
{ "beat": "journalbeat", "hostname": "example.lan", "name": "example.lan", "uuid": "34f6c6e1-45a8-4b12-9125-11b3e6e89866", "version": "7.15.2" }
Stats
edit/stats
reports internal metrics. Example:
curl -XGET 'localhost:5066/stats?pretty'
{ "beat": { "cpu": { "system": { "ticks": 1710, "time": { "ms": 1712 } }, "total": { "ticks": 3420, "time": { "ms": 3424 }, "value": 3420 }, "user": { "ticks": 1710, "time": { "ms": 1712 } } }, "info": { "ephemeral_id": "ab4287c4-d907-4d9d-b074-d8c3cec4a577", "uptime": { "ms": 195547 } }, "memstats": { "gc_next": 17855152, "memory_alloc": 9433384, "memory_total": 492478864, "rss": 50405376 }, "runtime": { "goroutines": 22 } }, "libbeat": { "config": { "module": { "running": 0, "starts": 0, "stops": 0 }, "scans": 1, "reloads": 1 }, "output": { "events": { "acked": 0, "active": 0, "batches": 0, "dropped": 0, "duplicates": 0, "failed": 0, "total": 0 }, "read": { "bytes": 0, "errors": 0 }, "type": "elasticsearch", "write": { "bytes": 0, "errors": 0 } }, "pipeline": { "clients": 6, "events": { "active": 716, "dropped": 0, "failed": 0, "filtered": 0, "published": 716, "retry": 278, "total": 716 }, "queue": { "acked": 0 } } }, "system": { "cpu": { "cores": 4 }, "load": { "1": 2.22, "15": 1.8, "5": 1.74, "norm": { "1": 0.555, "15": 0.45, "5": 0.435 } } } }
