Check Script

You can specify a check script like Keepalived script check to check if all the things is okay or not. The script will run for each VIP and gives an arg $1 that contains VIP.

Note: The script should be executable.

chmod +x check_script.sh

Sample Check Script

#!/usr/bin/env bash

ping $1 -c 1 -W 1

Support keepalived < 1.3.8

The collector use --signum to determine which signal to send to keepalived in order to retrieve stats/data. From keepalived release notes, this parameter has been added in version 1.3.8.

Unfortunately, the only version available in RHEL 7 and derivatives is 1.3.5. It seems that for this versions, the expected signals are USR1 for data, and USR2 for stats.

Would it be possible to add a failback to these signals if --signum is not supported ?

The exporter does not get any metrics

Hello,

I installed the exporter using the binary into /srv/ directory and I am using Keepalived v2.0.19 (10/19,2019) on Ubuntu Focal.

When I execute the exporter using a dedicated user, the exporter can't get any metrics :

# service keepalived-exporter status
systemd[1]: Started Keepalived Exporter Server.

When I execute the exporter as root, I get the following error :

panic: runtime error: index out of range [2] with length 1

Add some docs about the labels in the metrics to README

Exporter not working when keepalived container init doesn't handle keepalived signals

Currently, if docker mode is enabled, this exporter first checks signal numbers, by executing command in container: docker exec "${container-name}" keepalived --signum [STATS|DATA]. Related lines: https://github.com/cafebazaar/keepalived-exporter/blob/master/internal/types/container/keepalived_container_collector_host.go#L76-L104

It then uses those signal numbers to send them through docker to process with PID1 inside the container `docker kill : https://github.com/cafebazaar/keepalived-exporter/blob/master/internal/types/container/keepalived_container_collector_host.go#L106-L117

This unfortunately fails with osixia keepalived docker image, because it's init script doesn't relay these signals to keepalived instances it spawns osixia/docker-keepalived#50. While I believe this should be fixed in the keepalived image itself, maybe it could be considered to be handled in the exporter. I've chosen to use that docker image, because it seems most up to date.

The fix for this seems relatively simple - instead of running docker kill --signal 12 keepalived, one could run docker exec keepalived sh -c 'kill -12 "$( cat /var/run/keepalived.pid )"'. Of course this assumes that sh exists, so would probably require it to be a separate command line argument to switch between these 2 behaviors.

keepalived_vrrp_state

From your documentation, it says that keepalived_vrrp_state is supported, however, i don't see it being part of the metrics.
Is this the case or it is just on my implementation?

Semanti Pull Request doesn't check the commits from a PR as well

The check reacts to the PR title only. I guess we need a customized configuration file.

No keepalived_vrrp_state on Alpine

Running keepalived-exporter v1.2.0 on Alpine 3.16.2 doesn't return the keepalived_vrrp_state metric:

base on the README I started the keepalived-exporter with this command:
sudo keepalived-exporter
and it began to listen on port 9165.
then I curled curl localhost:9165/metrics
but the keepalived-exporter exited with these errors:

Keepalived Exporter stuck

In some cases when there is many prometheus to collect data from one exporter Keepalived Exporter will stuck.
I tried to reproduce this case with three prometheus to collect data with interval of 10s but it works!

Testing version: v0.1.1 Beta 1

Failed to parse VIP from keepalived data

Hi we have a two node keepalived cluster setup bevor haproxy. We are monitoring all components with prometheus and grafana and wanted to have the same for keepalived. That is we decided to try your solution.
We have downloaded the newest version of keepalived-exporter (1.0.1) and installed it on our server. After starting it we are getting the following message on the /metrics REST:

An error has occurred while serving metrics:

collected metric "keepalived_vrrp_state" { label:<name:"iname" value:"VI_1" > label:<name:"intf" value:"ens192" > label:<name:"ip_address" value:"141.249.3.160/32" > label:<name:"vrid" value:"52" > gauge:<value:2 > } was collected before with the same name and label values

On the console we are getting the following message:

sudo ./keepalived-exporter

Do you have any advice what the problem could be?

keepalived.data and keepalived.stats datas are not synced error

with old version (Keepalived v1.3.9 on Ubuntu 2018), the following error occured in random way and the metric keepalived_up is set to 0 but in fact the keepalived is running properly:

keepalived_exporter[80560]: time="2023-04-14T15:52:37+02:00" level=error msg="keepalived.data and keepalived.stats datas are not synced"

It's possible to just warn this error to support old version too ?

collector.go

if len(vrrpData) != len(vrrpStats) {
	logrus.Warn("keepalived.data and keepalived.stats datas are not synced: ", len(vrrpData), len(vrrpStats))
	// return nil, errors.New("keepalived.data and keepalived.stats datas are not synced")
}

if len(vrrpData) == len(vrrpStats) {
...
}

Which keepalived image is used?

Hi
Which keepalived image you used?

Thank you for your reply

can it support Keepalived and Keepalived Exporter on Linux?

why the keepalived.stats and keepalived.data is no data

Exporter crashes while it is running

I am catching a follow panic. Version of exporter is 1.0.0

panic: runtime error: index out of range [2] with length 1

My keepalived version is

Keepalived v2.2.4 (08/21,2021)

Occasional wrong result keepalived_up=0

Occasionally the exporter returns no keepalived metrics and keepalived_up = 0 even though the keepalived works fine.
In the exporter log there are lines

level=error msg="keepalived.data and keepalived.stats datas are not synced"
level=error msg="No data found to be exported" error="keepalived.data and keepalived.stats datas are not synced"

keepalived-exporter version 1.2.0 on Ubuntu 18.04.5 LTS,
keepalived version is 1.3.9 without support for JSON output, so stats/data is used.

One explanation could be that keepalived takes too long to write the stats or data file after the SIGSTATS/SIGDATA signal. Waiting 10 ms as in keepalived_container_collector_host.go:115 may not always be enough.

Multiple IPv4 interfaces with keepalived erroring out.

Hi ,
I have two virtual ipv4 interfaces (internal and external network). I am running the keepalived-exporter as a service . It works absolutely fine when there's just one interface. But with two interfaces, I am getting the following error when doing curl:

$ curl http://x.x.x.x:9165/metrics
An error has occurred while serving metrics:

collected metric "keepalived_script_status" { label:<name:"name" value:"chk_haproxy" > gauge:<value:1 > } was collected before with the same name and label values

---------- keepalived.conf-----------

vrrp_script chk_haproxy {
  script "/usr/bin/pgrep haproxy"
  interval 2 # every 2 seconds
  weight 2 # add 2 points if OK
}

vrrp_instance VI4_1 {
  interface eth0 

vrrp_instance VI4_2 {
  interface eth1 # interface to monitor

Should I change the internal code someplace so that it takes just one of the vrrp_instance instead ?

Make dump files thread safe

In a case of using 3 or more prometheus for HA and requesting at a same time Keepalived Exporter should make created files in /tmp thread safe.

Last release binary artifacts

Hi, I noticed that the releases are not updated since 2020, where can I get the latest binary?

The exporter requires to run as "root" to work

If I run it as a non root user, I get this error

prometheus@pgsyncslave:/home/sosuna/keepalived-exporter-1.0.0.linux-amd64$ curl localhost:9165/metrics
ERRO[0010] Failed to send signal                         error="operation not permitted" pid=12008
ERRO[0010] Failed to send STATS signal to keepalived     error="operation not permitted"
ERRO[0010] No data found to be exported                  error="operation not permitted" json=false

And the only metric returned is

keepalived_up 0

If I run it as "root" instead, the exporter works just fine. But obviously I don't wanna run it as root...

[Question] - Next release

Do you have a release date for v1.3.0 ?
As this release will include fix for keepalived_vrrp_state on keepalived v2.2.7 #88

Cannot start exporter

When I try to run the exporter, I get this fatal error

in the latest version of the exporter (1.3.1) the file /tmp/keepalived.data is not created automatically by the exporter, and it complains that the file doesn't exist.

keepalived-exporter time="2023-07-25T14:11:39Z" level=error msg="No data found to be exported" error="open /tmp/keepalived.data: no such file or directory"

keepalived-exporter time="2023-07-25T14:12:37Z" level=error msg="failed to open Script VRRP file" error="open /tmp/keepalived.data: no such file or directory" fileName=/tmp/keepalived.data

It works after I add the file manually (touch /tmp/keepalived.data)

Can you please have a look?

By the way the version is not correctly showing:

/keepalived-exporter -version
INFO[0000] Keepalived Exporter                           build_time= commit= version=

Update the release pipline

Use goreleaser instead.
Add docker build and push pipeline.
Update the docs accordingly.

Recurring warning about unkown script state with keepalived 1.3.5

Running keepalived-exporter 1.1.0 with keepalived 1.3.5 returns a recurring warning in the logs :

keepalived-exporter: time="2020-10-23T15:40:13+02:00" level=warning msg="Unknown state" name=node_status state=

It seems that the exporter tries to get the script state here : https://github.com/cafebazaar/keepalived-exporter/blob/7f70713c5b9d41121339e7e5195f91df9147fb1d/internal/collector/collector.go#L176

However, keepalived 1.3.5 does not expose this information in the data, only the status.

The warning can be safely ignored, but spam the logs with false positives.

Cannot start exporter: unexpected end of JSON input

Hi
When I try to run the exporter, I get this fatal error:

FATA[0000] Error unmarshalling signum result             error="unexpected end of JSON input" signal=DATA

I'm using version 1.0.3 of the exporter on centos7 and keepalived version 1.3.5

"Failed to open /tmp/keepalived.stats"

keeplaived version 1.3.5 - 1.3.9 (one host in 1.3.9 and 2 other in 1.3.5).

I have deployed keepalived-exporter as a service using the keepalived-exporter binary from the tar file on our keepalived/haproxy hosts.

Because of this missing keepalived.data file, we are not able to get the keepalived metrics even when the scrape is happening on correct port using endpoints.

missing vrid/intf value

Hi,

seems like the exporter doesn't populate vrid and interface value from the keepalived/config once the scraped

scrape example:
keepalived_vrrp_become_master{intf="",name="some_name",state="MASTER",vrid="0"} 1
keepalived_vrrp_become_master{intf="",name="some_name1",state="MASTER",vrid="0"} 1
keepalived_vrrp_become_master{intf="",name="some_name2",state="MASTER",vrid="0"} 1
