1 The following charts.d plugins are supported:
5 The plugin will monitor a squid server.
7 It will produce 4 charts:
9 1. **Squid Client Bandwidth** in kbps
15 2. **Squid Client Requests** in requests/sec
21 3. **Squid Server Bandwidth** in kbps
26 4. **Squid Server Requests** in requests/sec
33 The plugin will by itself detect squid servers running on
34 localhost, on ports 3128 or 8080.
36 It will attempt to download URLs in the form:
38 - `cache_object://HOST:PORT/counters`
39 - `/squid-internal-mgr/counters`
41 If any succeeds, it will use this.
45 If you need to configure it by hand, create the file
46 `/etc/netdata/squid.conf` with the following variables:
48 - `squid_host=IP` the IP of the squid host
49 - `squid_port=PORT` the port the squid is listening
50 - `squid_url="URL"` the URL with the statistics to be fetched from squid
51 - `squid_timeout=SECONDS` how much time we should wait for squid to respond
52 - `squid_update_every=SECONDS` the frequency of the data collection
54 Example `/etc/netdata/squid.conf`:
59 squid_url="cache_object://127.0.0.1:3128/counters"
68 The plugin will provide charts for all configured system sensors
70 > This plugin is reading sensors directly from the kernel.
71 > The `lm-sensors` package is able to perform calculations on the
72 > kernel provided values, this plugin will not perform.
73 > So, the values graphed, are the raw hardware values of the sensors.
75 The plugin will create netdata charts for:
85 One chart for every sensor chip found and each of the above will be created.
89 This is the internal default for `/etc/netdata/sensors.conf`
92 # the directory the kernel keeps sensor data
93 sensors_sys_dir="${NETDATA_HOST_PREFIX}/sys/devices"
95 # how deep in the tree to check for sensor data
98 # if set to 1, the script will overwrite internal
99 # script functions with code generated ones
100 # leave to 1, is faster
101 sensors_source_update=1
103 # how frequently to collect sensor data
104 # the default is to collect it at every iteration of charts.d
105 sensors_update_every=
112 The plugin will collect the postfix queue size.
114 It will create two charts:
116 1. **queue size in emails**
117 2. **queue size in KB**
121 This is the internal default for `/etc/netdata/postfix.conf`
124 # the postqueue command
125 # if empty, it will use the one found in the system path
128 # how frequently to collect queue size
129 postfix_update_every=15
136 The plugin will collect UPS data for all UPSes configured in the system.
138 The following charts will be created:
144 2. **UPS Battery Voltage**
151 3. **UPS Input Voltage**
157 4. **UPS Input Current**
161 5. **UPS Input Frequency**
166 6. **UPS Output Voltage**
174 8. **UPS Temperature**
176 * current temperature
181 This is the internal default for `/etc/netdata/nut.conf`
184 # a space separated list of UPS names
185 # if empty, the list returned by 'upsc -l' will be used
188 # how frequently to collect UPS data
