- Identify the problem. The first step in troubleshooting a device issue is to identify the problem, you have to consider if the issue is in NMIS8 or NMIS9 products.
- What kind of problem are you observing. A device issue can be affected for the next reasons.
- Network performance, latency in the network, layer 1,2, and 3 issues.
- Device configuration, connectivity, SNMP configuration, and others.
- Server hardware requirements, high resource utilization parameters in the server.
- Server configuration options, missing configuration items for server tunning.
- Disk performance, slow write/read times for the device collection.
- Gather information, collect all the graphs, images, behaviors that can explain what the problem is.
- Collect support tool files The Opmantek Support ToolThe Opmantek Support Tool

- If you are using NMIS8, provide the /usr/local/nmis8/var files
go to /usr/local/nmis8/var directory and collect the next files
