# IRC

This is what you will get:

IRCCloud web client:\

You need:

1.  The `nc` utility. If you do not set the path, Netdata will search for it in your system `$PATH`.

Set the path for `nc` in `/etc/netdata/health_alarm_notify.conf` (to edit it on your system run `/etc/netdata/edit-config health_alarm_notify.conf`), like this:

```
#------------------------------------------------------------------------------
# external commands
#
# The full path of the nc command.
# If empty, the system $PATH will be searched for it.
# If not found, irc notifications will be silently disabled.
nc="/usr/bin/nc"
```

2.  Αn `IRC_NETWORK` to which your preffered channels belong to.   
3.  One or more channels ( `DEFAULT_RECIPIENT_IRC` ) to post the messages to.   
4.  An `IRC_NICKNAME` and an `IRC_REALNAME` to identify in IRC.   

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:

```
#------------------------------------------------------------------------------
# irc notification options
#
# irc notifications require only the nc utility to be installed. 

# multiple recipients can be given like this:
#              "<irc_channel_1> <irc_channel_2> ..."

# enable/disable sending irc notifications
SEND_IRC="YES"

# if a role's recipients are not configured, a notification will not be sent.
# (empty = do not send a notification for unconfigured roles):
DEFAULT_RECIPIENT_IRC="#system-alarms"

# The irc network to which the recipients belong. It must be the full network.
IRC_NETWORK="irc.freenode.net"

# The irc nickname which is required to send the notification. It must not be 
# an already registered name as the connection's MODE is defined as a 'guest'.
IRC_NICKNAME="netdata-alarm-user"

# The irc realname which is required in order to make the connection and is an
# extra identifier.
IRC_REALNAME="netdata-user"
```

You can define multiple channels like this: `#system-alarms #networking-alarms`.\
You can also filter the notifications like this: `#system-alarms|critical`.\
You can give different channels per **role** using these (at the same file):  

```
role_recipients_irc[sysadmin]="#user-alarms #networking-alarms #system-alarms"
role_recipients_irc[dba]="#databases-alarms"
role_recipients_irc[webmaster]="#networking-alarms"
```

The keywords `#user-alarms`, `#networking-alarms`, `#system-alarms`, `#databases-alarms` are irc channels which belong to the specified IRC network.
