Simple Network Management Protocol - standard for monitoring and managing network devices. Like having a universal dashboard that monitors the health of all network equipment.
Network administrators use SNMP to monitor router performance and get alerts when devices experience problems.
SNMP is an open standard protocol (not a cloud service). In cloud environments, SNMP is typically used by third-party network monitoring tools (NMS) to poll devices/agents, while cloud-native monitoring services often use APIs and agents instead of SNMP.
