Features
The features added by this ZenPack be summarized as follows. They are each detailed further below.
- Initial discovery and continual synchronization of relevant components.
- Performance monitoring.
- Event management.
- Operational reports.
Discovery
The following components will be automatically discovered through the NetScaler address you provide. The properties and relationships will be continually maintained by way of SNMP Walks to the NetScaler device.
- Virtual Servers
- Attributes: State, Health, Services Up / Bound
- Relationships: Services, Service Groups
- Services
- Attributes: State
- Relationships: Virtual Servers, Servers, Service Groups (optional)
- Service Groups
- Attributes: State
- Relationships: Services
- Servers
- Attributes: State
- Relationships: Services, Service Groups
- Ethernet Interfaces
- Attributes: MAC Address, Operational Status, Admin Status
- Relationships: None
- VLANs
- Attributes: MAC Address
- Relationships: None
Performance Monitoring
The following metrics will be collected every 5 minutes by default. Any otherNetScaler metrics can also be collected by adding them to the appropriate monitoring template.
- Virtual Servers
- State: Down, Unknown, Busy, Out of Service (OOS), Transition to OOS, Up
- Current Connections: client, servers
- Total Requests/Responses: requests, responses
- Total Requests/Responses (bytes): requests, responses
- Total Received/Sent (packets): received, transmitted
- Current Services States: summation of service states
- Hits vs Misses: hits, misses
- Rates of Bytes: received, transmitted, requested
- Services
- State: Down, Unknown, Busy, Out of Service (OOS), Transition to OOS, Up
- Max Requests per Connection: Max
- Avg Transaction Time: Average
- Service Connections: Established, Active, Current
- Total Requests vs Responses: Requests, Responses
- Total Requests vs Responses (Bytes): Requests, Responses
- Total Packets Received vs Sent: Received, Transmitted
- Request Rate: Rate: Bytes Rate: Received, Transmitted
- Total Clients vs Servers: Clients, Servers, Max
- Active Transactions: Transactions
- Service Groups
- State: Disabled, Enabled;Servers: State: Down, Unknown, Busy, Out of Service (OOS), Transition to OOS, Up
- Ethernet Interfaces
- Utilization: Received, Transmitted
- Throughput (Data): Received, Transmitted
- Throughput (Packets): Rx'd/Tx'd Unicast, Rx'd/Tx'd Broadcast, Rx'd/Tx'd Multicast
- Errors: Rx'd/Tx'd Errors, Rx'd/Tx'd Discards
- VLANs
- Total Packets: Received, Transmitted, Dropped, Broadcast
- Total Bytes: Received, Transmitted
Event Management
The following event classes and their subclasses will be continually collected and passed into the Zenoss event management system.
- Alarm
- Event
- ExtendedEvent
- EventEx
Various information encoded in these event classes will be used to automatically determine as best as possible the following Zenoss event fields.
- Standard Zenoss Event Fields
- device (set to NetScaler device in the /Network/NetScaler device class)
- component
- summary
- severity
- eventClassKey (for mapping specific event types)
- eventKey (for de-duplication and auto-clear fingerprinting)
Events collected through this mechanism will be timestamped based on the time they occurred within NetScaler. Not by the time at which they were collected.

Troubleshooting
If any issues are encountered with the functionality offered by this ZenPack, the following checklist should be followed to verify that all configurations are correct.
Configuration Checklist
- Verify that Zenoss has been fully restarted after the ZenPack was installed.
- Verify that the NetScaler's address, username and password are correct.
- Verify that the NetScaler is connecting to the proper SNMP community (zProperty: zSnmpCommunity).
- Verify that the Zenoss collector server to which the endpoint device is assigned has network connectivity through any firewalls to the endpoint address on port 443/tcp (https).
- Check the logs.
Known Issues
The following issues have been identified in the most recent release of this ZenPack.
- (ZEN-9476) The first set of data for the components - services and virtual servers take 30 minutes
- After modeling NetScaler ZP, it presents the first set of data for Virtual LANs and Ethernet interfaces within usual 15 minutes. However, it takes 30 minutes to present the data for other components. There is no recommended work-around at this time.
Limitations
There is no service impact or root analysis available for the netscaler device.
