Hi,

In another project I use Telegram to receive push notifications on my phone so I thought it would be nice to have the same in NEMS.
It is actually quite simple to set this up.

For those interested, here are the steps:

1) Get a Telegram account (it is free!): https://telegram.org/
After setting up your account you will have a bot and a chat id.

2) install lua-sec (this will also install lua-socket):

Code:

sudo apt-get install lua-sec

3) Install the following script in /usr/local/bin:
Name the script 'telegram_nems.lua'
This is a simple lua script I wrote just to get this working, so it is really minimal without error checking etc...

Code:

#!/usr/bin/lua
https = require('ssl.https')
local telegram_url = 'https://api.telegram.org/<your bot>/sendMessage?'
local chat_id = '<your chat id>'

     Notification = "Notification Type: " .. arg[1] ..'\n'    --$NOTIFICATIONTYPE$
     Host = "Host: " .. arg[2] ..'\n'                         --$HOSTNAME$
     State = "State: " .. arg[3] ..'\n'                       --$HOSTSTATE$/$SERVICESTATE$
     Address = "Address: " .. arg[4] ..'\n'                   --$HOSTADDRESS$
     Info = "Info: "  .. arg[5] ..'\n'                        --$HOSTOUTPUT$/"$SERVICEOUTPUT$"
     Date_Time = "Date/Time: " .. arg[6] ..'\n'               --$LONGDATETIME$
   if (#arg == 6) then
     message = '***** Nagios ***** ' ..'\n' ..'\n' .. Notification .. Host ..State .. Address .. Info .. Date_Time
   else
     Service = "Service: " .. arg[7] .. '\n'                  --$SERVICEDESC$
     message = '***** Nagios ***** ' ..'\n' ..'\n' .. Notification .. Host  .. Service ..State .. Address .. Info .. Date_Time
   end

local data_str = 'chat_id=' .. chat_id .. '&text=' .. message..''  
local res, code, headers, status = https.request(telegram_url, data_str)

4) In NConf, add the following to Misccommands:

Code:

command_name                          notify-host-by-telegram
command_line                          /usr/local/bin/telegram_nems.lua "$NOTIFICATIONTYPE$" "$HOSTNAME$" "$HOSTSTATE$" "$HOSTADDRESS$" "$HOSTOUTPUT$" "$LONGDATETIME$"

Code:

command_name                          notify-service-by-telegram
command_line                          /usr/local/bin/telegram_nems.lua "$NOTIFICATIONTYPE$" "$HOSTNAME$" "$SERVICESTATE$" "$HOSTADDRESS$" "$SERVICEOUTPUT$" "$LONGDATETIME$" "$SERVICEDESC$"

As usual: use at your own risk!
