Wigo

Wigo, aka "What Is Going On" is a light pull/push monitoring tool written in Golang.

Main features

  • Write probes in any language you want
  • Notifications when a probe status change (http,email)
  • Proxy mode for hosts behind NAT/Gateways
  • Graphing probes metrics to OpenTSDB instances

Install Wigo Monitoring from Chrome Web Store

Installation

Warning : Breaking change since version 0.73.19 : A change in the wigo push protocol can cause crashes if your wigo push server version is < 0.73.22. You should update both wigo push clients and server to (at least) 0.73.22.

Debian :

Deb packages are available for Debian 9, 10 and 11

apt-get install lsb-release
wget -O- http://deb.carsso.com/deb.carsso.com.key | apt-key add -
echo "deb http://deb.carsso.com $(lsb_release --codename --short) main" > /etc/apt/sources.list.d/deb.carsso.com.list
apt-get update
apt-get install wigo

Debian 7 & 8 packages are not available anymore, it's time to upgrade :)

Centos :

Centos packages are not available anymore, but you can build them by yourself

Configuration / Setup

  • Wigo configuration is in /etc/wigo/wigo.conf
  • Probes configurations are in /etc/wigo/conf.d/
PULL

The master fetch remote clients over the http api. Communications should be secured using firewall rules, TLS and http basic authentication.

PUSH

Clients send their data to a remote master over a persistent tcp connection. Communications should be secured using firewall rules and TLS.

TLS

Wigo needs a key pair to enable HTTPS api. You can generate a self signed key pair by running this command:

/usr/local/wigo/bin/generate_cert -ca=false -duration=87600h0m0s -host "hostnames,ips,..." --rsa-bits=4096

Wigo needs a CA key pair to secure PUSH communications. You can generate a CA self signed key pair by running this command on the push server :

/usr/local/wigo/bin/generate_cert -ca=true -duration=87600h0m0s -host "hostnames,ips,..." --rsa-bits=4096
Default probes

The directory name is the interval of check in seconds

Building from sources

Environment

To build from sources, you need golang and gcc installed. The $GOPATH environment variable should also be set on your system.

Dependencies
make deps
Building for your system
make clean release
Building for all supported archs (amd64 & armhf)

You will need arm-linux-gnueabihf-gcc

make clean releases
Build debian packages

You will need reprepro

make debs
Build rpm packages

You will need rpm-building tools

cd build/rpm/
./makePackege.sh

Usage

Wigo web interface

http://[your-ip]:4000/ (by default)

Wigo CLI
# wigocli
Wigo v0.51.5 running on backbone.root.gg 
Local Status    : 100
Global Status   : 250

Remote Wigos : 

    1.2.3.4:4000 ( ns2 ) - Wigo v0.51.5: 
        apt-security              : 100  No security packages availables
        hardware_disks            : 250  Highest occupation percentage is 93% in partition /dev/md0
        hardware_load_average     : 100  0.09 0.04 0.05
        hardware_memory           : 100  Current memory usage is 19.32%
        ifstat                    : 100  tap0 0.00/0.01 mbps , eth1 0.00/0.00 mbps , eth0 0.01/0.01 mbps ,

Write your own probes !

Probes are binaries, written in any language you want, that output a json string with at least Status param :

$ ./hardware_load_average
{
   "Detail" : "",
   "Version" : "0.11",
   "Message" : "0.38 0.26 0.24",
   "Status" : 100,
   "Metrics" : [
      {
         "Value" : 0.38,
         "Tags" : {
            "load" : "load5"
         }
      },
      {
         "Value" : 0.26,
         "Tags" : {
            "load" : "load10"
         }
      },
      {
         "Value" : 0.24,
         "Tags" : {
            "load" : "load15"
         }
      }
   ]
}

    100         OK
    101 to 199  INFO
    200 to 299  WARN
    300 to 499  CRIT
