+# fping.plugin
+
+The fping plugin supports monitoring latency, packet loss and uptime of any number of network end points,
+by pinging them with `fping`.
+
+A recent version of `fping` is required (one that supports option ` -N `).
+The supplied plugin can install it, by running:
+
+```sh
+/usr/libexec/netdata/plugins.d/fping.plugin install
+```
+
+The above will download, build and install the right version as `/usr/local/bin/fping`.
+
+Then you need to edit `/etc/netdata/fping.conf` (to edit it on your system run
+`/etc/netdata/edit-config fping.conf`) like this:
+
+```sh
+# uncomment the following line - it should already be there
+fping="/usr/local/bin/fping"
+
+# set here all the hosts you need to ping
+# I suggest to use hostnames and put their IPs in /etc/hosts
+hosts="host1 host2 host3"
+
+# override the chart update frequency - the default is inherited from netdata
+update_every=1
+
+# time in milliseconds (1 sec = 1000 ms) to ping the hosts
+# 200 = 5 pings per second
+ping_every=200
+
+# other fping options - these are the defaults
+fping_opts="-R -b 56 -i 1 -r 0 -t 5000"
+```
+
+## alarms
+
+netdata will automatically attach a few alarms for each host.
+Check the [latest versions of the fping alarms](https://github.com/netdata/netdata/blob/master/health/health.d/fping.conf)
+
+## Additional Tips 
+
+### Customizing Amount of Pings Per Second
+
+For example, to update the chart every 10 seconds and use 2 pings every 10 seconds, use this:
+
+```sh
+# Chart Update Frequency (Time in Seconds)
+update_every=10
+
+# Time in Milliseconds (1 sec = 1000 ms) to Ping the Hosts
+# The Following Example Sends 1 Ping Every 5000 ms
+# Calculation Formula: ping_every = (update_every * 1000 ) / 2
+ping_every=5000
+```
+
+### Multiple fping Plugins With Different Settings
+
+You may need to run multiple fping plugins with different settings for different end points.
+For example, you may need to ping a few hosts 10 times per second, and others once per second.
+
+netdata allows you to add as many `fping` plugins as you like.
+
+Follow this procedure:
+
+**1. Create New fping Configuration File**
+
+
+```sh
+# Step Into Configuration Directory
+cd /etc/netdata
+
+# Copy Original fping Configuration File To New Configuration File
+cp fping.conf fping2.conf
+```
+
+Edit `fping2.conf` and set the settings and the hosts you need for the seconds instance.
+
+**2. Soft Link Original fping Plugin to New Plugin File**
+
+```sh
+# Become root (If The Step Step Is Performed As Non-Root User)
+sudo su
+
+# Step Into The Plugins Directory
+cd /usr/libexec/netdata/plugins.d
+
+# Link fping.plugin to fping2.plugin
+ln -s fping.plugin fping2.plugin
+```
+
+That's it. netdata will detect the new plugin and start it.
+
+You can name the new plugin any name you like.
+Just make sure the plugin and the configuration file have the same name.
