What views are most popular for a quick network health overview? Tips from fellow engineers and sysadmins for starting your day well informed.

We have asked sysadmins and network engineers how they quickly get on track with their network health at the beginning of the day. Do they run the NetCrunch console for a brief checkup or mostly rely on alerts to guide your day and fire up NetCrunch only to perform certain tasks? Learn about their answers below.

1. Active alerts

Not surprisingly, most engineers mention the active alerts window as the first one they study when opening the administration console in the morning. After a brief glimpse at the network atlas summary to check for any obvious burning points, the next task is usually going through and clearing the alarms generated overnight; some alarms need just simple acknowledgment, others could require more hands-on attention. Active alerts view helps concentrate on what’s still a problem and may need to be taken care of by one of the IT team members.

Depending on your IT team structure, you may have resource owners that want to receive only messages from the devices/servers used in their daily business. One of the IT managers recommends determining the alarms that each team member is responsible for, based on relevant monitoring packs. She set up different notifications based on the alarm levels (critical, warn & info), and then she could control how those notifications were sent to users (email or SMS, repeating or not). For example, when they stand up a new SQL instance, it was defined as a new node, got the SQL pack assigned and the resource owners would start getting their required notifications.

2. Custom network views and maps

Several admins mention how much they rely on custom network views. One of the admins likes being able to roll his own views for SNMP data. He has customized views for NetApp storage appliances, and Cisco ASA’s. For example, he has included a storage SNMP event for the NetApp storage appliances to receive warnings when disk space is low on a CIFS share or iSCSI LUN. These types of warnings are available via SMS, email, and visually on the NetCrunch map. Another engineer finds custom maps very handy for performing certain tasks, such as a custom view for UPS’es that displays the status of all monitored UPS’s in one glance. He has created similar views for Windows servers, Cisco switches, and storage appliances as well.

A network engineer responsible for a school network recalls how layer 2 maps and switch port maps help him win over some students’ tricks who repeatedly try loosening network cables on classroom printers just enough to disconnect them but the cables are still in the socks so it does not look disconnected on the outside. Another problem he mentioned was LAN connectors that would paralyze the network at the cores with a short circuit, these were daily occurrences that he needed to be alerted about and fix on the spot. He found port mapping views useful for fast troubleshooting and localizing the disconnected cable and going directly to a particular printer to reattach it. He knew each part of the network, having built it himself, but automatic switch port maps helped him transfer his network knowledge, especially when preparing for his retirement and training a new colleague to take over his responsibilities.

3. Top charts

Top charts are often called a standup event — it is an urban legend among our integrators and consultants that whenever they install a trial version of NetCrunch at the potential customer site and display top charts view for the local network, one of the engineers present at the meeting quickly stands up and rushes out of the meeting room to fix or check something in the network. NetCrunch users like the fact that they can customize top charts to filter out slow but less important devices (such as workstations or devices from the test lab) and have a top chart view with critical resources automatically sorted by most utilized/slowest/drained etc.

After identifying the most problematic nodes, systems, or services in your network, you can analyze their performance in the alert analytics window, which can help you identify nodes that may work right now but their overall performance is spotty or you wish to take a longer look to decide if you need to plan or prepare some action related to them in the near future.

4. Alerts: Analytics window

The analytics window gives you a broader insight into what’s going on with your critical devices — for example, take a closer look at a node that is on again, off again frequently, and investigate the reason for it. You might not detect this fact in the active alerts window because when the node goes up, it clears the ‘down’ event and it is no longer visible in the active alerts view. But in the analytics view, you could see the list of all alerts for this node and drill down to the root cause of this behavior.

5. Monitoring issues

Finally, in the neverending quest to the all-green network status dashboard, monitoring issues view help identify resources that need your intervention to make it possible for NetCrunch to collect their health metrics. Whether it is incorrect or missing password, or insufficient access right, monitoring issues is the view that helps you verify that your monitoring coverage is complete. It makes sense to check this window to finetune your monitoring and make sure that NetCrunch has all the necessary credentials and rights to track the data that you want it to. You can select multiple nodes at once if you want to assign them the same credentials.
