Squid Prometheus exporter
--------------------------
Exports squid metrics in Prometheus format
**NOTE**: From release 1.0 metric names and some parameters has changed. Make sure you check the docs and update your deployments accordingly!
New
-----
* Using environment variables to configure the exporter
* Adding custom labels to metrics
* Enabling TLS for exporter via [WebConfig](https://github.com/prometheus/exporter-toolkit/blob/master/docs/web-configuration.md)
Usage:
------
Simple usage:
squid-exporter -squid-hostname "localhost" -squid-port 3128
[Configure Prometheus](https://github.com/boynux/squid-exporter/blob/master/prometheus/prometheus.yml) to scrape metrics from `localhost:9301/metrics`
- job_name: squid
# squid-exporter is installed, grab stats about the local
# squid instance.
target_groups:
- targets: ['localhost:9301']
To get all the parameteres, command line arguments always override default and environment variables configs:
squid-exporter -help
The following environment variables can be used to override default parameters:
```
SQUID_EXPORTER_LISTEN
SQUID_EXPORTER_WEB_CONFIG_PATH
SQUID_EXPORTER_METRICS_PATH
SQUID_HOSTNAME
SQUID_PORT
SQUID_LOGIN
SQUID_PASSWORD
SQUID_EXTRACTSERVICETIMES
```
Usage with docker:
------
Basic setup assuming Squid is running on the same machine:
docker run --net=host -d boynux/squid-exporter
Setup with Squid running on a different host
docker run -p 9301:9301 -d boynux/squid-exporter -squid-hostname "192.168.0.2" -squid-port 3128 -listen ":9301"
With environment variables
docker run -p 9301:9301 -d -e SQUID_PORT="3128" -e SQUID_HOSTNAME="192.168.0.2" -e SQUID_EXPORTER_LISTEN=":9301" boynux/squid-exporter
Build:
--------
This project is written in Go, so all the usual methods for building (or cross compiling) a Go application would work.
If you are not very familiar with Go you can download the binary from [releases](https://github.com/boynux/squid-exporter/releases).
Or build it for your OS:
`go install https://github.com/boynux/squid-exporter`
then you can find the binary in: `$GOPATH/bin/squid-exporter`

FAQ:
--------
- Q: Metrics are not reported by exporter
- A: That usually means the exporter cannot reach squid server or the config manager permissions are not set corretly. To debug and mitigate:
- First make sure the exporter service can reach to squid server IP Address (you can use telnet to test that)
- Make sure you allow exporter to query the squid server in config you will need something like this (`172.20.0.0/16` is the network for exporter, you can also use a single IP if needed):
```
#http_access allow manager localhost
acl prometheus src 172.20.0.0/16
http_access allow manager prometheus
```
- Q: Why `process_open_fds` metric is not exported?
- A: This usualy means exporter don't have permission to read `/proc/<squid_proc_id>/fd` folder. You can either
1. _[recommended]_ Set `CAP_DAC_READ_SEARCH` capability for squid exporter process (or docker). (eg. `sudo setcap 'cap_dac_read_search+ep' ./bin/squid-exporter`)
2. _[not recommended]_ Run the exporter as root.

sessionAffinity: ClientIP
# Service settings below are applicable only if
# service.type is one of [LoadBalancer, NodePort] and not ClusterIP.
# Possible values are [Cluster, Local].
# If set to Local, then the Service's port will be available only on Kubernetes
# Nodes which have the Squid Pods so no Kubernetes Node-to-Node traffic will be forwarded.
# If set to Cluster, then the Service's port will be available on any Node of
# a Kubernetes cluster. The drawback is that Kubernetes will use double NAT
# so it will hide the Client source IP from Squid.
externalTrafficPolicy: Cluster
# Node port to listen on. Typically, Kubernetes allows ports in range 30000-32767
# see https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport
