Yes, Uptime Infrastructure Monitor uses a series of different background applications, all of which are multi-threaded. This includes the following applications:
- Apache. The UIM Apache engine spawns several instances, each of which will run on separate CPUs, if available.
- MySQL. The UIM MySQL engine spawns a single process that will run multiple queries across as many CPUs as possible. At times, the MySQL threading may need tuning via the concurrent_threads MySQL system variable. Generally, two concurrent threads per CPU core are recommended.
- Java. The UIM data collector is Java-based. Java is inherently multi-threaded, so UIM service monitors and other tasks will be spread across many CPUs.
