I kept disabling checks and then would get caught up in something else and forgot what I disabled.
I created these scripts to remind me what is disabled so I can go back, fix the problem if needed,
and re-enable the notifications.
To use these, you need to cat the status.log and pipe it into the script:

'cat status.log | host_status.awk'

I run a bash script on a cron to call these two scripts and send the output via email:

echo "Nothing is disabled..."

Hi, Can you please advise on how to run this on Ubuntu? When I run it as documented I get no result. This is also after confirming the location of awk is not in /bin/awk but in /usr/bin/awk (which was updated in the script).

It seems that the version of nagios I have also has a status.dat file, with no status.log file. Maybe I'm missing something here, but it seems different when installed on Ubuntu (or Debian).
I will re-release this script with all of its requirements:

This script will convert output to html email and provide a html link to enable service/host

#!/bin/bash

DATE=$(date +%c)

NAGIOS_STATUS="/var/nagios/status.dat"
WORKING_DIR="/usr/local/bin"


SUBJECT="Disabled Nagios notifications *** $DATE"
from="sender@domain.com"
SENDMAIL_FOLDER="$WORKING_DIR/sendmail"
RCPT="reciever@domain.com"
BODY="$HOST $SERVICE"

userpass="nagiosadmin:password"
nagios_server="nagios.server.yourdomain.com"

function host_status() {
awk -v user=$userpass -v server=$nagios_server 'BEGIN { header=0; FS="="; } /^[[:space:]]*info {[[:space:]]*$/ { codeblock="info"; } /^[[:space:]]*program {[[:space:]]*$/ { codeblock="program"; } /^[[:space:]]*hoststatus {[[:space:]]*$/ { codeblock="host"; host_name=""; notifications_enabled=""; } /^[[:space:]]*service {[[:space:]]*$/ { codeblock="service"; } /^[[:space:]]*host_name=/ { host_name=$2; } /^[[:space:]]*notifications_enabled=/ { notifications_enabled=$2; } /^[[:space:]]*}[[:space:]]*$/ { if (codeblock=="host" && notifications_enabled=="0") { if (header==0) { print "The following hosts have notifications disabled:"; header=1; } print ""host_name"ENABLE NOTIFICATION"; } } '

}


function service_status() {
awk -v user=$userpass -v server=$nagios_server 'BEGIN { header=0; FS="="; } /^[[:space:]]*info {[[:space:]]*$/ { codeblock="info"; } /^[[:space:]]*program {[[:space:]]*$/ { codeblock="program"; } /^[[:space:]]*hoststatus {[[:space:]]*$/ { codeblock="host"; } /^[[:space:]]*servicestatus {[[:space:]]*$/ { codeblock="service"; host_name=""; service_description=""; notifications_enabled=""; } /^[[:space:]]*host_name=/ { host_name=$2; } /^[[:space:]]*service_description=/ { service_description=$2; } /^[[:space:]]*notifications_enabled=/ { notifications_enabled=$2; } /^[[:space:]]*}[[:space:]]*$/ { if (codeblock=="service" && notifications_enabled=="0") { if (header==0) { print "The following services have notifications turned off"; header=1; } print ""service_description " on " host_name"ENABLE SERVICE NOTIFICATION"; } } '
}






HOST=$(/bin/cat $NAGIOS_STATUS| host_status)
SERVICE=$(/bin/cat $NAGIOS_STATUS |service_status)

if [[ -n $HOST || -n $SERVICE ]]; then
cd $SENDMAIL_FOLDER;./sendmail.pl "$WORKING_DIR" "$from" "$RCPT" "$SUBJECT:" "$SERVICE$HOST"

Awesome, great for a busy admin.

I put together a awk a to check if nofitications are disabled globally.


BEGIN { header=0;
FS="=";
}

/^[[:space:]]*info {[[:space:]]*$/ {
codeblock="info";
}

/^[[:space:]]*programstatus {[[:space:]]*$/ {
codeblock="program";
notifications_enabled="";
}

/^[[:space:]]*hoststatus {[[:space:]]*$/ {
codeblock="host";
}

/^[[:space:]]*servicestatus {[[:space:]]*$/ {
codeblock="service";
}

/^[[:space:]]*enable_notifications=/ {
notifications_enabled=$2;
}

/^[[:space:]]*}[[:space:]]*$/ {
if (codeblock=="program" && notifications_enabled=="0") {
if (header==0) {
print "
******************
Notifications have been disabled globally!!!!!!!
";

header=1;
}
print host_name;
}
}

Figure that might be useful to someone
I have the same exact problem, so this really helped. Had to adjust it a bit, maybe to fit the recent version? Also, tweaked a bit to have line breaks between hosts/services.. Here are my cents:

host_status.awk:
1c1
#!/bin/awk -f
30c30
/^[[:space:]]*host {[[:space:]]*$/ {
36c36
/^[[:space:]]*service {[[:space:]]*$/ {

service_status.awk:
1c1
#!/bin/awk -f
30c30
/^[[:space:]]*host {[[:space:]]*$/ {
34c34
/^[[:space:]]*service {[[:space:]]*$/ {
36d35
Thanks for contributing to Nagios exchange. Its a good and handy tool for nagios Admin. 100% recommended.
