+# squid
+
+This module will monitor 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
+
+```yaml
+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

+# netdata python.d.plugin configuration for squid
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+# - global variables
+# - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+# name: myname # the JOB's name as it will appear at the
+# # dashboard (by default is the job_name)
+# # JOBs sharing a name are mutually exclusive
+# update_every: 1 # the JOB's data collection frequency
+# priority: 60000 # the JOB's order on the dashboard
+# retries: 60 # the JOB's number of restoration attempts
+# autodetection_retry: 0 # the JOB's re-check interval in seconds
+#
+# Additionally to the above, squid also supports the following:
+#
+# host : 'IP or HOSTNAME' # the host to connect to
+# port : PORT # the port to connect to
+# request: 'URL' # the URL to request from squid
+#
+
+# ----------------------------------------------------------------------
+# SQUID CONFIGURATION
+#
+# See:
+# http://wiki.squid-cache.org/Features/CacheManager
+#
+# In short, add to your squid configuration these:
+#
+# http_access allow localhost manager
+# http_access deny manager
+#
+# To remotely monitor a squid:
+#
+# acl managerAdmin src 192.0.2.1
+# http_access allow localhost manager
+# http_access allow managerAdmin manager
+# http_access deny manager
+#
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
