How to view logs from previous rules executions?

Help
1

We use the “Real-time Webtask Logs” to stream logs, and it works great.

But how can we setup something more production friendly, so we can monitor the logs in production efficiently?

We use papertrail - but anything would be better than nothing.

Hi @alexab,

The extension is mostly intended for debugging. You would have to set up some external logging if you want something more persistent.

Hope this clarifies things,

Hi @dan.woda

Thanks for answering.

Ok, I will look into possible solution for papertrail then…

Let us know how it goes!

Ok, so here is a small guide to make this work:

Step 1, create a new log destination at Papertrail. Make sure to choose “Token” authentication.

Step 2, copy the token and create a new Auth0 rule secret

Step 3, add the following code in your rule (or something similar):

function aSimpleRule(user, context, callback) {
    let messages = ``;
    const crypto = require('crypto');
    const randomId = crypto.randomBytes(20).toString('hex');
    const customLogger = (message) => {
        // Log the message the console + internal buffer
        console.log(message);
        messages += `${randomId} ${context.request.hostname} | ${message}\n`;
    };
    // HELPER FUNCTION TO ENABLE LOGGING
    const reportLogToPapertrail = () => {
        const fetch = require('node-fetch');
        fetch('https://logs.collector.solarwinds.com/v1/logs', {
            method: 'post',
            headers: {
                'Content-Type': 'text/plain',
                Authorization: `Basic ${configuration.LOG_KEY}`,
            },
            body: messages,
        })
            .then((res) => {
                console.log(
                    `Successfully reported messages to Papertrail with status '${res.status}'`
                );
                return res.text();
            })
            .then((text) => {
                console.log(text);
            })
            .catch((err) =>
                console.log(
                    `Failed reporting error to Papertrail with '${err.message}' - not good!`
                )
            );
    };

    customLogger('some message');
    customLogger('another message');
    reportLogToPapertrail(); // Make sure that you don't await this
    callback(null, user, context)
}

This will send a batch request with all the logs, nicely formatted in papertrail, while the real-time logs still work. Enjoy :innocent:
