 - SNMPv2c credential profiles with encrypted community strings.
 - Guided SNMP device discovery with friendly device, interface, and monitorable item results.
 - Asset setup supports creating, selecting, and deleting assets, plus attaching ping, TCP, website, and SNMP monitors without creating alert rules automatically.
+- Worker collects configured SNMP uptime, interface status, traffic counter, error, and discard monitors.

-Current completed items include TLS expiry monitor support, HTTP/website checks, ping and TCP port checks, basic alert evaluation, alert rule editing UI, incident actions, webhook notification channels, SNMPv2c credential profiles, the SNMP device discovery API, guided SNMP discovery UI, and asset-based monitor setup. The next recommended implementation work is SNMP collection for configured SNMP monitors and friendly metric/profile mapping.
+Current completed items include TLS expiry monitor support, HTTP/website checks, ping and TCP port checks, basic alert evaluation, alert rule editing UI, incident actions, webhook notification channels, SNMPv2c credential profiles, the SNMP device discovery API, guided SNMP discovery UI, asset-based monitor setup, and initial SNMP collection for uptime plus interface counters/status. The next recommended implementation work is SNMP profile mapping and expanded CPU, memory, storage, and sensor collection.
