I'm currently trying to set up nagios herald on my production nagios instance. I've made all the setup neccessary and when I run the following dry run, the notification is sent straight away:
root#mon1 objects]# /usr/local/nagios-herald/bin/nagios-herald
--env-file /tmp/test_herald.out --message-type email -r my.email#address.net --formatter=$_SERVICEMESSAGE_FORMATTER_NAME$
--nagios-cgi-url=http://192.168.0.1/nagios/cgi-bin/cmd.cgi --reply-to=nagios#somehost.com
I want to be able to test keeping my legacy notifications in place, so I created a new command, contactgroup, and contact definition:
define command {
command_name herald-service-email
command_line /usr/local/nagios-herald/bin/nagios-herald --message-type email -r my.email#address.net --formatter=$_SERVICEMESSAGE_FORMATTER_NAME$ --nagios-cgi-url=http://192.168.0.1/nagios/cgi-bin/cmd.cgi --reply-to=nagios#somehost.com
}
# nagios herald testing
define contactgroup {
contactgroup_name nagios-herald
alias nagios herald
name nagios-herald
members nagios-herald
}
define contact {
contact_name nagios-herald
alias nagios-herald
name nagios-herald
use generic-pager
service_notification_commands herald-service-email
register 1
email my.email#address.net
}
Lastly, I added the service notification command to my global contact used for all our alerting (the alert email is aliased to our actual email in /etc/aliases:
define contact {
contact_name admin
alias admin user
name admin
register 1
host_notification_period 24x7
host_notification_options d,u,r
host_notification_commands notify-host-by-email
service_notification_period 24x7
service_notification_options w,u,c,r
service_notification_commands notify-service-by-email,dump-env,herald-service-email
email admin
pager admin-pager
}
And I see the notification getting invoked in my Thruk web UI, so I'm at a loss as to how/why this isn't working when the command invoked manually works. Anyone have any ideas or suggestions?
Can you provide one of the service definitions you're expecting to see an alert from? Perhaps you have a malformed _message_formatter_name directive.
You can also append the --trace argument to the end of the nagios-herald notification command and it will provide more details on what it's doing. Remember to also set -l <logfile> in the command or specify logfile: in the config so the output is captured in a file.

I am trying to set up some monitoring for my host. I know that I can access it via the macro $HOSTADDRESS$, but how can I actually append the correct string to it? The $HOSTADDRESS$ won't return anything on just the root (so nothing on /), but I want it rather to check on /health-check. Is it possible to append the /health-check to $HOSTADDRESS$ somehow?
Using Opsview 6, which is based on Nagios.
You can pass the change to check_http in your service description
check_http --help
...
-u, --url=PATH
URL to GET or POST (default: /)
...
check_command check_http!--url=/health-check
mngmt-users.properties file. The users are added in the file but when I try to run the localhost it says it's running then if I try to view the admin console it is redirecting to http://localhost:9990/error/index_win.html. That tells the server is running but I could not open admin console.

I have to send a mail with an attachment from a shell script.
I am trying to do it using mutt as shown here: How do I send a file as an email attachment using Linux command line?
Command:
echo "This is the message body" | mutt -a "/path/to/file.to.attach" -s "subject of message" -- recipient#domain.com
Error:
Error sending message, child exited 127 (Exec error.). Could not send
the message.
I was having the same issue on Ubuntu 18.04 and just like #jono, I only had installed mutt. Installing
sudo apt-get install sendmail
After that, sending mail with the test method or straight through the mutt CLI worked perfectly.
I have encountered this same error today.
I found I only had mutt installed, but once I installed sendmail this error went away. However I then got blocked locally.
So I uninstalled sendmail, and installed postfix this worked..
Now receiving email with attached pdf.
This was on RHEL 7.4 in an enterprise environment. Unsure if results will differ on other versions or environments.
I had this error and had to simply add below to my .muttrc. I'm using Gmail if that matters. This way I'm using someone elses server to send and don't have to install extra junk.
set smtp_pass="secrets"
set smtp_url = "smtps://username#gmail.com#smtp.gmail.com:465/"
set the password generated from this link into this file:

set realname="first_name last_name"

Fix for GMail Account Configuration
The following post worked for me: https://www.codyhiar.com/blog/getting-mutt-setup-with-gmail-using-2-factor-auth-on-ubuntu-14-04/
But it was not very clear. The contents of ~/.muttrc that worked for me are as follows (My account has 2-Step verification enabled and I had to generate app password as described in the post):
set imap_user = "<username>#gmail.com"
set imap_pass = "<16-character-app-password>"
set sendmail="/usr/sbin/ssmtp"
set folder="imaps://imap.gmail.com:993"
set spoolfile="imaps://imap.gmail.com/INBOX"
set record="imaps://imap.gmail.com/[Gmail]/Sent Mail"
set postponed="imaps://imap.gmail.com/[Gmail]/Drafts"
set header_cache = "~/.mutt/cache/headers"
set message_cachedir = "~/.mutt/cache/bodies"
set certificate_file = "~/.mutt/certificates"
set from = "<username>#gmail.com"
set realname = "<name-used-in-the-gmail-account>"
set smtp_url = "smtp://<username>#smtp.gmail.com:587/"
set smtp_pass="<16-character-app-password>"
set move = no
set imap_keepalive = 900
# Gmail-style keyboard shortcuts
macro index,pager ga "<change-folder>=[Gmail]/All<tab><enter>" "Go to all mail"
macro index,pager gi "<change-folder>=INBOX<enter>" "Go to inbox"
macro index,pager gs "<change-folder>=[Gmail]/Starred<enter>" "Go to starred messages"
macro index,pager gd "<change-folder>=[Gmail]/Drafts<enter>" "Go to drafts"
macro index,pager e "<enter-command>unset trash\n <delete-message>" "Gmail archive message" # different from Gmail, but wanted to keep "y" to show folders.
Replace the following:
<username>: Your gmail username
<16-character-app-password>: You have to generate this
<name-used-in-the-gmail-account>: Your name as per gmail account
Note: Don't change <change-folder>
I'm trying to find a way for an email notification in awstats.
The idea is that whenever there's an error (missing log files, statistics couldn't be generated) an email with an error message should be send to a specific email address.
I already found the config-Attribute "ErrorMessages" but as far as i get it its just for displaying an error.
Is there an attribute like "ErrorMessages" for activating mail notifications or do i have to implement it myself?
You can use cron job to run awstats update proccess.
And it'll sent update process result via email to you.
Example:
* * * * * /usr/local/awstats/update.sh | mail abc#xzy.com
I found a way to trap Errors while my code is executed. It's not an awstats feature, more a generic way:
Inside my script:
#Error Handling
set -e
function sendErrorNotification(){
echo "Awstats: An error occured during processing server logs." | mail -s "AWSTATS ERROR" "...#..."
}
trap sendErrorNotification EXIT
....code goes here...
set +e
trap - EXIT
We have a part of a mail filter that denies emailing system accounts for security purposes. We recently had a user created that ends in "bin". The bin user is restricted, but the user, lets say l.parrbin, gets flagged via the syntax below:
my #sysaccounts = qw(
root bin daemon adm lp sync shutdown halt mail
news uucp operator games gopher ftp nobody nscd
vcsa rpc mailnull smmsp apache pcap ntp dbus
avahi rpcusder nfsnobody sshd haldaemon xfs defang
clamav monit mysql decode webmaster mailer-daemon
nagios
);
foreach $acct(#sysaccounts){
if ($recip =~ /$acct\#/i){
md_syslog('info', 'Sysaccount Discard');
return('REJECT', "We do not accept messages to system accounts ($acct)");
}
}
How would I prevent the above code from returning REJECT if a name ends or starts with a name from the sysaccounts?
Try doing this :
if ($recip =~ /^$acct\#/i){
# ^
In regex, ^ is an anchor meaning beginning of line (string here)
