Verify PacketWise Health

Instructions to use a PacketShaper to investigate the health and state of the unit itself.

Available Capacity

PacketWise has several types of capacity limits that can impact your ability to expand your traffic management solution. For example, if you run out of traffic classes or matching rules, you won't be able to auto-discover or add any new types of traffic.

It's a good idea to check your unit(s)' available capacities every few months or whenever you have made lots of configuration changes (such as changes to your traffic class tree, your policies and partitions, the amount of traffic your network supports, the number of units with Xpress enabled, and so on).

You can check estimates of system boundaries based on unit model. Keep in mind these are rough estimates of maximum limits that vary with real-time conditions.

You can check your real-time system limits with the CLI command called sys limits.

You'll see results similar to these:  show screen.

If you find that your are running out of capacity, there are a variety of remedies, depending on which item and which unit model you have. You can:

• Upgrade to a larger model. For some models, such as the 2500 and 8500, you can upgrade by simply by purchasing a new software key that enables more classes.
• Consider trimming your traffic tree. Often, the traffic class tree gets full because auto-discovery creates a lot of classes for traffic that passed only once. You can go through the class tree and delete these unnecessary classes to free space.
• Consult information in Packeteer's Best Practices website under the section called Extend.
• Contact Packeteer's support organization for help.

Trouble Alerts

PacketWise's adaptive response feature automatically monitors for conditions of interest, detects potential problems, and optionally notifies somebody and/or takes corrective actions if a problem is detected.

You can keep tabs on many aspects of PacketWise health at all times without frequent investigations. See Monitor and Respond to Conditions of Interest and consider making use of the System Load, Unit Limits, Memory Allocation agents in the Unit Health group.
