Which open source software or SaaS service in spirit of timber.io, logentries, papertrail etc. would you recommend for searching JSON-based logs generated from several processes?<p>In my current setup, each process is running on the same machine, so it could be something very simple.
Take a look at NXLog Community Edition. It has a great set of features, Open Source and free. <a href="https://nxlog.co" rel="nofollow">https://nxlog.co</a>
logdna.com is great. Has good pricing, a lot of endpoints and great support.
We had created a small Objective C wrapper around their REST endpoint to have remote logging, and they sent us some “Thank you T-shirt’s”<p>Other contender is Google Stackdriver, but I did not check the pricing policy they have now
