ix. Impact of Procedure: CISSDM TAC will have no visibility into customer nodes monitored via ICMP or SNMP in SolarWinds NPM. CISSDM TAC will continue to have visibility and alerts for nodes monitored via API (including Meraki, Viptella, Velocloud, etc...) during this maintenance window.
x. Roll Back procedure: CISSDM IT will take a database backup several hours before the maintence window. This backup will not impact operations of the NPM system. CISSDM IT will take snapshots of all impacted infrastructure, and should we run into a major issue, we will roll-back the entire infrastructure to the snapshots, and then review further after return of services for a root cause analysis.
