We've been using the SLACK notification driver for a while to send basic text, with the most advanced formatting to date being simple bold highling of certain text elements. This is done by just putting * around text i.e.
*this part is bold* this part is not
But I want to actually post with different colours, perhaps even with fancy attachments, but for now I just want to stick with colors
Is it possible with the included SLACK driver?
I've tried simply parsing this as text
{"attachments": [{"color": "#ad03fc","text": "Optional text that appears within the attachment"}]}
which pasting it in here shows is valid syntax https://api.slack.com/docs/messages/builder
but I just get the literal text in the SLACK channel. I don't know how the included driver actually works to perhaps further modify the syntax so it works
Any help?
Alternatively can NetXMS do a HTTP Put? because if so I know how to make that work, we already do fancy formatting with Solarwinds that way
In current implementation of slack driver it creates a simple json like this:
{"channel":"C061EG9SL","text":"mesage_text"}
so anything you write just goes into "text" field. An ability to generate custom jsons would require to make quite some changes in slack notification channel code.
Ok so the SLACK driver is not going to be able to support fancy formatting beyond anything that can be expressed in regular text, i.e. bolding
However can NetXMS do a HTTP PUT? As that would allow me to post whatever I want. As mentioned before this is how we get fancy formatting from Solarwinds NCM as it pushes to slack via a HTTP PUT operation
You can create action that "executes command on the management server" and call curl in that action.
I know nothing about curl or executing commands from NetXMS. So is this the correct syntax to put into the 'command' box?
curl -d "{"attachments": [{"color": "#ad03fc","text": "Example message from node %n message is %m %M"}]}" -X PUT http://{SLACK URL}
Was close. This is the correct syntax
curl -d 'payload={"attachments": [{"color": "#36a64f","text": "Text example from node %n message is %m %M"}]}' -X PUT https://{SLACK WEBHOOK URL}
