This doesn't answer your question, but is running the script from cron and having it send the email notification not an option?

Hi folks,

I have recently created a script to figure out which users on the local system have expired accounts.  So anyone returned by the script output will be a user account that is expired and can't login.  And if they have a star (*) by their name the account is older than 90 days.

When I get back the alert email, the description not only has my script output but it also contains its own little info line.

My script output is just:

3 inactive accounts: *user1, user2, *user3

But When I get an alert it looks like this:

Description: '/usr/local/sbin/' failed with exit status (1) -- 3 inactive accounts: *user1, user2, *user3

Monit adds this extra line: '/usr/local/sbin/' failed with exit status (1) --

Does anyone know how to instruct Monit to exclude this line from the $DESCRIPTION field?  I just want the output like this:

Description: 3 inactive accounts: *user1, user2, *user3

Here is the way I have entered configuration declaration into Monit.

check program inactive-accounts with path "/usr/local/sbin/"
  every "0-3 6 * * *"
  alert address@hidden not on { instance, action }
  if status != 0 then alert

# vim: ft=config

I'm running monit from EPEL and the version is: monit-5.14-1.el6.x86_64.

I don't suppose it matters a lot, but just in case, here is the script.


# Let's get a list of accounts likely to be people, not service accounts
_accounts=`getent --service=files passwd | awk -F: '$3 > 500 && $1 !~ /splunk|service|oracle|nobody|nails/'`

# What to call the array of inactive accounts
declare -a inactiveAccounts

# Today's date
_todaysDateInDaysSince1970=`echo \`date +%s\`/86400 | bc`

# Now let's see who's account is inactive, and add it to the array
for _row in $_accounts ; do
  _user=`echo $_row | awk -F: '{print $1}'`
  _accountExpirationInDaysSince1970=`getent --service=files shadow $_user | awk -F: '{print $8}'`
  if (("$_todaysDateInDaysSince1970" > "$_accountExpirationInDaysSince1970")); then
    if (("$(($_todaysDateInDaysSince1970-$_accountExpirationInDaysSince1970))" > "90")); then

# Create a printout suitable for Monit reporting
printf "Found address@hidden inactive accounts: "
for _user in address@hidden; do
  if (("$_i" > "0")); then
    printf ","
  printf "$_user"
  (( _i += 1 ))
printf "\n"

# Exit code of 0 for Success (no inactive accounts)
# Exit code of 1 for Alert (inactive accounts)
if [ "address@hidden" -eq "0" ]; then
  exit 0
elif (( "address@hidden" >= "1" )); then
  exit 1

Thanks in advance for any hint or info in the right direction.
