mtail VS datadog-agent

You can do that with something like mtail. Basically write expressions that match your logs and produce metrics.

mtail is a standard tool for this.

I use goflow2 to do something like this. I don't specifically use syslog itself for this, but mtail to generate the metrics.

I can recommend mtail. Here is a good example nginx script.

Convert your logs to metrics with mtail.

For nginx, you'll need to setup a log parser like mtail because it doesn't really have much for metrics to begin with.

mtail is an option if you have a set number of URLs. You'll need to either scrape the data it provides with prometheus, or send it to collectd, statsd, graphite, etc.

Same thing with metrics, use mtail to parse dhcp logs. This way you can see graphs of requests and errors. Plus you can now write alerts for it in Prometheus.

I use mtail. In addition to the real-time mode, you can also run it in "one shot" mode to count matches.

I'm a fan of mtail for extracting data from logs. This fits well with the overall Prometheus Monitoring monitoring that I use.

It's worse than that, they want security through obscurity too. They feel like someone is inappropriately tinkering with the agent they want customers to install.

Serverless developers have the benefit of cloud providers deploying new features which improve our experience and reduce costs. Recently AWS introduced Graviton for Lambda, which leverages their custom ARM-based processor. Using Graviton, AWS says that users can see 19% better performance at 20% lower cost - and many users wouldn't even have to change any of their code at all! At my day job at DataDog, we quickly rolled out ARM-compatible versions of the DataDog Extension and our IaC integrations like the Serverless Plugin and the CDK Construct.

The worse is when many are intermixed, and usually glued together in unconventional ways. Like https://github.com/DataDog/datadog-agent where there's a go, c++, and python build.
