+# megacli
+
+Module collects adapter, physical drives and battery stats.
+
+**Requirements:**
+ * `megacli` program
+ * `sudo` program
+ * `netdata` user needs to be able to be able to sudo the `megacli` program without password
+
+To grab stats it executes:
+ * `sudo -n megacli -LDPDInfo -aAll`
+ * `sudo -n megacli -AdpBbuCmd -a0`
+
+
+It produces:
+
+1. **Adapter State**
+
+2. **Physical Drives Media Errors**
+
+3. **Physical Drives Predictive Failures**
+
+4. **Battery Relative State of Charge**
+
+5. **Battery Cycle Count**
+
+### prerequisite
+This module uses `megacli` which can only be executed by root. It uses
+`sudo` and assumes that it is configured such that the `netdata` user can
+execute `megacli` as root without password.
+
+Add to `sudoers`:
+
+ netdata ALL=(root) NOPASSWD: /path/to/megacli
+
+### configuration
+
+**megacli** is disabled by default. Should be explicitly enabled in `python.d.conf`.
+```yaml
+megacli: yes
+```
+
+Battery stats disabled by default. To enable them modify `megacli.conf`.
+```yaml
+do_battery: yes
+```

+# netdata python.d.plugin configuration for megacli
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+
+# ----------------------------------------------------------------------
+# 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, megacli also supports the following:
+#
+# do_battery: yes/no # default is no. Battery stats (adds additional call to megacli `megacli -AdpBbuCmd -a0`).
+#
+# ----------------------------------------------------------------------
+# uncomment the line below to collect battery statistics
+# do_battery: yes
