We use a combination of splunk, solarwinds' server & application monitoring and new relic. We're about to start using prometheus for monitoring some apps that we've moved into containers. We also have several thousand monitors/alerts that are setup in ipmonitor that we're trying to get moved over to sam.
For just logs, LogDNA is fast and cheap.<p>For everything else, Datadog has the best setup although their agent is old and messy, but they have logging coming soon and some basic APM integration.<p>If kubernetes, try Sysdig or Netsil.
I highly recommend checking out Blue Medora products (full disclosure: I work there). We offer world class monitoring products across a lot products and platforms.
