ERROR log to telegram or somewhere else
-
In case of apear certain words on logs, it send that log line with some basic data to the manager get notifications as soon as an Error happends.
-
Invitation to an experiment: Try to find out if this works ...
Cloudron api -> n8n -> some magic -> TelegramIMHO it should be possible to get all the information (https://docs.cloudron.io/api.html#tag/Eventlog)
Challenge accepted?
-
Out of curiosity I've built what @luckow suggested, only with Cloudron API (notifications endpoint) -> n8n -> some magic -> ntfy.sh-app and it looks like this:
-
Action gets triggered (either automatically or manually), n8n checks the cloudron api
https://my.example1.com/api/v1/notifications(create a readonly access token in your profile and update the Bearer token with it) with the parametersacknowledged=false, so only unread notifications are collected. -
The code-node does the following (
filteredTitlesbecause I don't care about app-updates, only actual issues, can be adjusted of course):
const notifications = items[0].json.notifications; const types = notifications.map(notification => notification.type); const titles = notifications.map(notification => notification.title); // Filter notifications to remove those with type "appUpdated" const filteredNotifications = notifications.filter(notification => notification.type != "appUpdated"); // Extract titles of the filtered notifications const filteredTitles = filteredNotifications.map(notification => notification.title); //return [{ json: { types, titles } }]; return [{ json: { filteredTitles } }];This will result in an array of current notifications, e.g.
[ { "filteredTitles": [ "Email is not configured properly", "The app at cms.example.com ran out of memory." ] } ]- The if-node checks if there's actual content. If it's empty, nothing will happen, if it's not, it will make a http request to your nfty instance and topic of your choice (saved credentials in n8n) and send the notifications:
Since I was working with readonly tokens, I had no intentions of marking the notifications as read after sending out the message. So there's room for improvement, but I thought I would throw it in here as a PoC

Improvements are welcome!
TL;DR: Adjust the URLs to your Cloudrons, create and add readonly tokens, add a
ntfy tokento your n8n credentials and adjust the URL to your ntfy instance. -

In case anyone needs it, I added support to dismiss the notification.
After the if node, assuming true, add another connection, a 'Loop over items' node, with a batch size of 1.
Connect the node's "loop" connection to a new function node with this code.
// Access the input JSON data const item = $json; // Ensure the structure is correct and 'filteredID' exists if (item.filteredID && Array.isArray(item.filteredID) && item.filteredID.length > 0) { const notificationId = item.filteredID[0]; // Extract the first ID // Return the data for the HTTP Request node return { json: { notificationId: notificationId, acknowledged: true } }; } else { throw new Error("Invalid JSON structure or 'filteredID' not found."); }Then, connect the function node to a new HTTP request node with the method of 'POST', URL of "https://my.cloudron.site/api/v1/notifications/{{ $json.notificationId }}" (As an expression), same authorization header as the first HTTP request nodes, with the (JSON) body of:
{ "acknowledged": true }I'm pretty sure this process can be written better, but this approach was quick and dirty. I've also adjusted the notifications to be sent via email rather than using NFTY, but that's a pretty straightforward step.
