Customize Notification HTML Email - mail.py

[stanislas93]

Hello,

I would like your opinion.

Problem 1 : I have configured a notification Notification Method (HTML Email) but I do not have the link to my Service note URL in my notification email.

My solution 1 : I modified the check_mk_templates.cfg file and added

define command {
command_name check-mk-notify
command_line \

   NOTIFY_SERVICENOTESURL='$SERVICENOTESURL$' \

Question 1 : Is this the right method?

Problem 2 : Now the link appears but is not clickable

My Solution 2 : I modified the /opt/omd/versions/2.2.0p20.cre/lib/python3/cmk/notification_plugins/mail.py file and I edited this section

(
“notesurl”,
“service”,
False,
“all”,
“Custom Service Notes URL”,
“$SERVICENOTESURL$”,
“$SERVICENOTESURL$”,
),

by

(
    "notesurl",
    "service",
    False,
    "all",
    "Custom Service Notes URL",
    "$SERVICENOTESURL$",
    "<a href=$SERVICENOTESURL$>$SERVICENOTESURL$</a>",
),

now the link is clickable

Question 2 : Is this the right method?

Problem 3 : in my link I have a # and he is transformed into %23

Question 3 : can I change the encoding?

I think whatever I did is not the right method because if I do an update of checkmk I lose everything. I tried to follow Andrea’s solution : Change resolution of graphs in mail notifications - #4 by kaiserchrss

I do it on my systems the following way.

copy ~/lib/python/cmk/notifications/mail.py to ~/local/lib/python
copy ~/share/check_mk/notifications/mail to ~/local/share/check_mk/notifications
modify line 2 of ~/local/share/check_mk/notifications/mail - append a “modified” or something else
also change the import line to import mail
modify the ~/local/lib/python/mail to your needs

my solution that doesn’t work :

1 - I created a file/opt/omd/sites/mysite/local/share/check_mk/notifications/mail

HTML Email 2

from cmk.notification_plugins import mail

if name == “main”:
mail.main()

2 - I also have to copy /opt/omd/versions/2.2.0p20.cre/lib/python3/cmk/notification_plugins/mail.py but where?
I have to put it in the same tree?

cd /opt/omd/sites/mysite/local/lib/

ll

python/
python3/

cd python or python3?

In python3/cmk/ i create notification_plugins folder and copy mail.py and modify it?

thank you in advance

I’m not perfectly sure, but don’t these settings in the standard notification rule work for you:

Thanks for you answer Dirk

Insert HTML section* insert a link in the email before the notification

there is a link behind “Host” and “Service” but not behind “Custom Service Notes URL” and an encoding problem in the link

I think everything you need contains the Service Rule “Notes URL for Services”. Fine Grained you can setup the “Custom Services Notes URL” for your Notifications. I had no issues when Links contain “#”. For example:

No customisations. Everything “out of the box”. Tested on 2.1.0p36.cee. Not sure if this rule exists in cre:

Hi,

My version is check-mk-raw-2.2.0p20-el9-38.x86_64

I will explain all my steps.

Step 1 : I created a notification

Step 2 : I created a note URL for services

Step 3 : My first notification does not have the link of my note URL for services

Step 4 : I modified the check_mk_templates.cfg file and added “SERVICENOTESURL”

define command {
command_name check-mk-notify
command_line
…
NOTIFY_SERVICENOTESURL=‘$SERVICENOTESURL$’
…

Step 5 : my second notification have the link to my “note URL for services” but is not clickable and there is an encoding problem with the #

Step 6 :

I modified the /opt/omd/versions/2.2.0p20.cre/lib/python3/cmk/notification_plugins/mail.py file and I edited this section

(
“notesurl”,
“service”,
False,
“all”,
“Custom Service Notes URL”,
“$SERVICENOTESURL$”,
“$SERVICENOTESURL$”,
),

by

(
“notesurl”,
“service”,
False,
“all”,
“Custom Service Notes URL”,
“$SERVICENOTESURL$”,
"<a href=$SERVICENOTESURL$>$SERVICENOTESURL$</a>",

),

Step 7 : My third notification has the link to my “note URL for services” and is now clickable and there is still an encoding problem with the #

Here are all my steps to have the link clickable

Is this the right method, I don’t think… your opinions are welcome?

Hi,

Do you have another solution to prevent my changes from being overwritten on the next checkmk update?
