Squid collector

Monitors one or more squid instances depending on configuration.

It produces following charts:

1. Client Bandwidth in kilobits/s

   • in
   • out
   • hits

2. Client Requests in requests/s

   • requests
   • hits
   • errors

3. Server Bandwidth in kilobits/s

   • in
   • out

4. Server Requests in requests/s

   • requests
   • errors

Configuration

Edit the python.d/squid.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/squid.conf

priority     : 50000

local:
  request : 'cache_object://localhost:3128/counters'
  host    : 'localhost'
  port    : 3128

Without any configuration module will try to autodetect where squid presents its counters data

Troubleshooting

To troubleshoot issues with the squid module, run the python.d.plugin with the debug option enabled. The output will give you the output of the data collection job or error messages on why the collector isn't working.

First, navigate to your plugins directory, usually they are located under /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/
sudo su -s /bin/bash netdata

Now you can manually run the squid module in debug mode:

./python.d.plugin squid debug trace
