- 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.
- Add to the support the case the product version and the servers/devices/models involved.
- 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 Tool
Execute the collect command for the support tool
Code Block #General collection. /usr/local/nmis8/admin/support.pl action=collect #If the file is big, we can add the next parameter. /usr/local/nmis8/admin/support.pl action=collect maxzipsize=900000000 #Device collection. /usr/local/nmis8/admin/support.pl action=collect node=<node_name> maxzipsize=900000000
- If you are using NMIS8, provide the /usr/local/nmis8/var files
go to /usr/local/nmis8/var directory and collect the next files
Code Block -rw-rw---- 1 nmis nmis 4292 Apr 5 18:26 <node_name>-node.json -rw-rw---- 1 nmis nmis 2695 Apr 5 18:26 <node_name>-view.json
obtain update/collect outputs this information will upload to the support case:
Code Block /usr/local/nmis8/bin/nmis.pl type=update node=<node_name> model=true debug=9 force=true > /tmp/node_name_update_$(hostname).log /usr/local/nmis8/bin/nmis.pl type=collect node=<node_name> model=true debug=9 force=true > /tmp/node_name_collect_$(hostname).log
- Collect support tool files The Opmantek Support Tool
- Replicate the problem. If possible you have to define, what the steps are to replicate the problem.
- Identify symptoms. To this point, you are able to see a specific problem and what the symptoms are.
- Determinate if something has changed, is important to verify with your team if some change is performed something has changed, a good way to see this behavior is monitoring the performance graph for devices and server
- It It is an individual problem?, verify if this behavior is happening in a single device/server.
