Analyzing Netdata outputĪs observable in the image above, Netdata provides constant QOS data for each of your devices. Monitoring your connection is done via analyzing Netdata output and alarms. Wait 10 minutes and then check the fping section at Monitoring your connection With a dedicated RPi 3 you can reach almost a constant stream by setting update_every to 1 and ping_every to 20. The reason I've chosen these frequencies is that my trusty old RPi is already pre-occupied doing other things, and a higher rate proved to consume too many resources. # fping will not allow this to be below 20ms # by default 5 pings per host per iteration # The time in milliseconds (1 sec = 1000 ms) to ping the hosts
INTERNET UPTIME MONITOR ALTERNATIVE.TO UPDATE
We'll setup Netdata to ping all of these in bursts of 5 pings, each 3.3 minutes, and display information in a 10 minutes interval: # The update frequency of the chart in minutes - the default is inherited from netdata Hosts="SWITCH_IP ROUTER_IP GATEWAY_IP 8.8.8.8" # we suggest to put names here and the IPs of these names in /etc/hosts Here you'll need to enter the individual IP addresses of all of your home network equipment, as well as the WAN IP address we're using to validate internet access ( 8.8.8.8 in our case): # a space separated list of hosts to fping Now edit the fping configuration: $ nano nf This is done using a built in script: $ cd /etc/netdata/ With Netdata, monitors are installed simply by copying templates from /usr/lib/netdata/ to /etc/netdata/.
INTERNET UPTIME MONITOR ALTERNATIVE.TO INSTALL
Let's make sure fping is installed: $ fping -vįping: comments to it's not available, simply install it: $ sudo apt install -y fping We're gonna do this by having Netdata ping all hops periodically using fping. It's important to remember that our goal is to monitor all the home network equipment as well as the internet gateway. Now browse to and you should see Netdata in action: Setting up network monitoring with fping Let's restart Netdata: $ sudo systemctl restart netdata We're not gonna deal with securing Netdata from outside access. # Netdata is not designed to be exposed to potentially hostile Update the file with your correct Ip address: Then edit Netdata's configuration: $ nano /etc/netdata/nf Let's find out the RPi's IP address: $ hostname -I | awk '' We need to make sure Netdata is binding to the right IP address.

We want to monitor each and every hop (i.e. I monitor connectivity and QOS by pinging the network equipment. Is it my ISP that's cutting service? Maybe the router is lagging behind? Should I change an RJ cable or switch providers?Ī few colleagues have expressed interest in how I monitor my own connectivity using a simple RPi 1 B+, so I've decided to simply share. But a simple binary check won't suffice.Įven with a simple setup like I have at home - some switches and routers and an ISP modem - it's hard to identify which of the components is causing a QOS issue or even completely disconnects me from the internet. Working from home has raised the importance of monitoring my internet connectivity.
