# Rocket.Chat This is what you will get:  You need: 1. The **incoming webhook URL** as given by RocketChat. You can use the same on all your Netdata servers (or you can have multiple if you like - your decision). 2. One or more channels to post the messages to. Get them here: Set them in `/etc/netdata/health_alarm_notify.conf` (to edit it on your system run `/etc/netdata/edit-config health_alarm_notify.conf`), like this: ``` #------------------------------------------------------------------------------ # rocketchat (rocket.chat) global notification options # multiple recipients can be given like this: # "CHANNEL1 CHANNEL2 ..." # enable/disable sending rocketchat notifications SEND_ROCKETCHAT="YES" # Login to rocket.chat and create an incoming webhook. You need only one for all # your Netdata servers (or you can have one for each of your Netdata). # Without it, Netdata cannot send rocketchat notifications. ROCKETCHAT_WEBHOOK_URL="" # if a role's recipients are not configured, a notification will be send to # this rocketchat channel (empty = do not send a notification for unconfigured # roles). DEFAULT_RECIPIENT_ROCKETCHAT="monitoring_alarms" ``` You can define multiple channels like this: `alarms systems`. You can give different channels per **role** using these (at the same file): ``` role_recipients_rocketchat[sysadmin]="systems" role_recipients_rocketchat[dba]="databases systems" role_recipients_rocketchat[webmaster]="marketing development" ``` The keywords `systems`, `databases`, `marketing`, `development` are RocketChat channels (they should already exist). Both public and private channels can be used, even if they differ from the channel configured in your RocketChat incoming webhook. [](<>)
