From a64a253794ac64cb40befee54db53bde17dd0d49 Mon Sep 17 00:00:00 2001 From: Daniel Baumann Date: Wed, 7 Nov 2018 13:19:29 +0100 Subject: New upstream version 1.11.0+dfsg Signed-off-by: Daniel Baumann --- charts.d/README.md | 344 ----------------------------------------------------- 1 file changed, 344 deletions(-) delete mode 100644 charts.d/README.md (limited to 'charts.d/README.md') diff --git a/charts.d/README.md b/charts.d/README.md deleted file mode 100644 index 748af08a1..000000000 --- a/charts.d/README.md +++ /dev/null @@ -1,344 +0,0 @@ -The following charts.d plugins are supported: - ---- - -# hddtemp - -The plugin will collect temperatures from disks - -It will create one chart with all active disks - -1. **temperature in Celsius** - -### configuration - -hddtemp needs to be running in daemonized mode - -```sh -# host with daemonized hddtemp -hddtemp_host="localhost" - -# port on which hddtemp is showing data -hddtemp_port="7634" - -# array of included disks -# the default is to include all -hddtemp_disks=() -``` - ---- - -# libreswan - -The plugin will collects bytes-in, bytes-out and uptime for all established libreswan IPSEC tunnels. - -The following charts are created, **per tunnel**: - -1. **Uptime** - - * the uptime of the tunnel - -2. **Traffic** - - * bytes in - * bytes out - -### configuration - -Its config file is `/etc/netdata/charts.d/libreswan.conf`. - -The plugin executes 2 commands to collect all the information it needs: - -```sh -ipsec whack --status -ipsec whack --trafficstatus -``` - -The first command is used to extract the currently established tunnels, their IDs and their names. -The second command is used to extract the current uptime and traffic. - -Most probably user `netdata` will not be able to query libreswan, so the `ipsec` commands will be denied. -The plugin attempts to run `ipsec` as `sudo ipsec ...`, to get access to libreswan statistics. - -To allow user `netdata` execute `sudo ipsec ...`, create the file `/etc/sudoers.d/netdata` with this content: - -``` -netdata ALL = (root) NOPASSWD: /sbin/ipsec whack --status -netdata ALL = (root) NOPASSWD: /sbin/ipsec whack --trafficstatus -``` - -Make sure the path `/sbin/ipsec` matches your setup (execute `which ipsec` to find the right path). - ---- - -# mysql - -The plugin will monitor one or more mysql servers - -It will produce the following charts: - -1. **Bandwidth** in kbps - * in - * out - -2. **Queries** in queries/sec - * queries - * questions - * slow queries - -3. **Operations** in operations/sec - * opened tables - * flush - * commit - * delete -

-You can configure many database servers, like this: - -You can provide, per server, the following: - -1. a name, anything you like, but keep it short -2. the mysql command to connect to the server -3. the mysql command line options to be used for connecting to the server - -Here is an example for 2 servers: - -```sh -mysql_opts[server1]="-h server1.example.com" -mysql_opts[server2]="-h server2.example.com --connect_timeout 2" -``` - -The above will use the `mysql` command found in the system path. -You can also provide a custom mysql command per server, like this: - -```sh -mysql_cmds[server2]="/opt/mysql/bin/mysql" -``` - -The above sets the mysql command only for server2. server1 will use the system default. - -If no configuration is given, the plugin will attempt to connect to mysql server at localhost. - - ---- - -# nut - -The plugin will collect UPS data for all UPSes configured in the system. - -The following charts will be created: - -1. **UPS Charge** - - * percentage changed - -2. **UPS Battery Voltage** - - * current voltage - * high voltage - * low voltage - * nominal voltage - -3. **UPS Input Voltage** - - * current voltage - * fault voltage - * nominal voltage - -4. **UPS Input Current** - - * nominal current - -5. **UPS Input Frequency** - - * current frequency - * nominal frequency - -6. **UPS Output Voltage** - - * current voltage - -7. **UPS Load** - - * current load - -8. **UPS Temperature** - - * current temperature - - -### configuration - -This is the internal default for `/etc/netdata/nut.conf` - -```sh -# a space separated list of UPS names -# if empty, the list returned by 'upsc -l' will be used -nut_ups= - -# how frequently to collect UPS data -nut_update_every=2 -``` - ---- - -# postfix - -The plugin will collect the postfix queue size. - -It will create two charts: - -1. **queue size in emails** -2. **queue size in KB** - -### configuration - -This is the internal default for `/etc/netdata/postfix.conf` - -```sh -# the postqueue command -# if empty, it will use the one found in the system path -postfix_postqueue= - -# how frequently to collect queue size -postfix_update_every=15 -``` - ---- - -# sensors - -The plugin will provide charts for all configured system sensors - -> This plugin is reading sensors directly from the kernel. -> The `lm-sensors` package is able to perform calculations on the -> kernel provided values, this plugin will not perform. -> So, the values graphed, are the raw hardware values of the sensors. - -The plugin will create netdata charts for: - -1. **Temperature** -2. **Voltage** -3. **Current** -4. **Power** -5. **Fans Speed** -6. **Energy** -7. **Humidity** - -One chart for every sensor chip found and each of the above will be created. - -### configuration - -This is the internal default for `/etc/netdata/sensors.conf` - -```sh -# the directory the kernel keeps sensor data -sensors_sys_dir="${NETDATA_HOST_PREFIX}/sys/devices" - -# how deep in the tree to check for sensor data -sensors_sys_depth=10 - -# if set to 1, the script will overwrite internal -# script functions with code generated ones -# leave to 1, is faster -sensors_source_update=1 - -# how frequently to collect sensor data -# the default is to collect it at every iteration of charts.d -sensors_update_every= - -# array of sensors which are excluded -# the default is to include all -sensors_excluded=() -``` - ---- - -# squid - -The plugin will monitor a squid server. - -It will produce 4 charts: - -1. **Squid Client Bandwidth** in kbps - - * in - * out - * hits - -2. **Squid Client Requests** in requests/sec - - * requests - * hits - * errors - -3. **Squid Server Bandwidth** in kbps - - * in - * out - -4. **Squid Server Requests** in requests/sec - - * requests - * errors - -### autoconfig - -The plugin will by itself detect squid servers running on -localhost, on ports 3128 or 8080. - -It will attempt to download URLs in the form: - -- `cache_object://HOST:PORT/counters` -- `/squid-internal-mgr/counters` - -If any succeeds, it will use this. - -### configuration - -If you need to configure it by hand, create the file -`/etc/netdata/squid.conf` with the following variables: - -- `squid_host=IP` the IP of the squid host -- `squid_port=PORT` the port the squid is listening -- `squid_url="URL"` the URL with the statistics to be fetched from squid -- `squid_timeout=SECONDS` how much time we should wait for squid to respond -- `squid_update_every=SECONDS` the frequency of the data collection - -Example `/etc/netdata/squid.conf`: - -```sh -squid_host=127.0.0.1 -squid_port=3128 -squid_url="cache_object://127.0.0.1:3128/counters" -squid_timeout=2 -squid_update_every=5 -``` -- cgit v1.2.3
