# APC UPS
Plugin: charts.d.plugin
Module: apcupsd
## Overview
Monitor APC UPS performance with Netdata for optimal uninterruptible power supply operations. Enhance your power supply reliability with real-time APC UPS metrics.
The collector uses the `apcaccess` tool to contact the `apcupsd` daemon and get the APC UPS statistics.
This collector is supported on all platforms.
This collector only supports collecting metrics from a single instance of this integration.
### Default Behavior
#### Auto-Detection
By default, with no configuration provided, the collector will try to contact 127.0.0.1:3551 with using the `apcaccess` utility.
#### Limits
The default configuration for this integration does not impose any limits on data collection.
#### Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
## Metrics
Metrics grouped by *scope*.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
### Per ups
Metrics related to UPS. Each UPS provides its own set of the following metrics.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| apcupsd.charge | charge | percentage |
| apcupsd.battery.voltage | voltage, nominal | Volts |
| apcupsd.input.voltage | voltage, min, max | Volts |
| apcupsd.output.voltage | absolute, nominal | Volts |
| apcupsd.input.frequency | frequency | Hz |
| apcupsd.load | load | percentage |
| apcupsd.load_usage | load | Watts |
| apcupsd.temperature | temp | Celsius |
| apcupsd.time | time | Minutes |
| apcupsd.online | online | boolean |
| apcupsd.selftest | OK, NO, BT, NG | status |
| apcupsd.status | ONLINE, ONBATT, OVERLOAD, LOWBATT, REPLACEBATT, NOBATT, SLAVE, SLAVEDOWN, COMMLOST, CAL, TRIM, BOOST, SHUTTING_DOWN | status |

## Setup
### Prerequisites
#### Install charts.d plugin
If [using our official native DEB/RPM packages](https://github.com/netdata/netdata/blob/master/packaging/installer/UPDATE.md#determine-which-installation-method-you-used), make sure `netdata-plugin-chartsd` is installed.
#### Required software
Make sure the `apcaccess` and `apcupsd` are installed and running.
### Configuration
#### File
The configuration file name for this integration is `charts.d/apcupsd.conf`.
You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config charts.d/apcupsd.conf
```
#### Options
The config file is sourced by the charts.d plugin. It's a standard bash file.
The following collapsed table contains all the options that can be configured for the apcupsd collector.
Config options
| Name | Description | Default | Required |
|:----|:-----------|:-------|:--------:|
| apcupsd_sources | This is an array of apcupsd sources. You can have multiple entries there. Please refer to the example below on how to set it. | 127.0.0.1:3551 | no |
| apcupsd_timeout | How long to wait for apcupsd to respond. | 3 | no |
| apcupsd_update_every | The data collection frequency. If unset, will inherit the netdata update frequency. | 1 | no |
| apcupsd_priority | The charts priority on the dashboard. | 90000 | no |
| apcupsd_retries | The number of retries to do in case of failure before disabling the collector. | 10 | no |
#### Examples
##### Multiple apcupsd sources
Specify a multiple apcupsd sources along with a custom update interval
```yaml
# add all your APC UPSes in this array - uncomment it too
declare -A apcupsd_sources=(
["local"]="127.0.0.1:3551",
["remote"]="1.2.3.4:3551"
)
# how long to wait for apcupsd to respond
#apcupsd_timeout=3
# the data collection frequency
# if unset, will inherit the netdata update frequency
apcupsd_update_every=5
# the charts priority on the dashboard
#apcupsd_priority=90000
# the number of retries to do in case of failure
# before disabling the module
#apcupsd_retries=10
```
## Troubleshooting
### Debug Mode
To troubleshoot issues with the `apcupsd` collector, run the `charts.d.plugin` with the debug option enabled. The output
should give you clues as to why the collector isn't working.
- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.
```bash
cd /usr/libexec/netdata/plugins.d/
```
- Switch to the `netdata` user.
```bash
sudo -u netdata -s
```
- Run the `charts.d.plugin` to debug the collector:
```bash
./charts.d.plugin debug 1 apcupsd
```
