Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: SLAs, SLIs, and SLOs, SNMP polling and traps, agents, agentless checks, webhooks, and health checks, thresholds and alerts, and performance symptoms: memory and swap, load average, steal time, disk latency, packet drops, and throughput, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.
Preview the topics
- A storage array must warn the monitoring server at once when a disk fails, without waiting for the next poll. What should it send?
- The on-call team gets hundreds of disk alerts each week, and most clear on their own within a minute. The team has started to ignore them. What should change?
- A virtual machine is slow, and its load average is high. top shows a high steal time, while its own programs use little processor time. What is the likely cause?
