• Streamlined rediscovery process when interface index shifts occur.
• Streamlined rediscovery behavior during snmpcollector restart.
• Enhanced verbose logging to log stack traces when exceptions occur.
• Pollagent now restarts all delta calculations for a device when the device transitions from unreachable to reachable.
• Previously, the probe would attempt to calculate a delta with the last value read before the device became unreachable.
• Created a pollagent self-health monitor to provide overall insight and increase the resiliency of pollagent. The Poller SpecialDebug.log file continually logs thread counts that are greater than 100. The probe reads this file and restarts if threads are unavailable for longer than 15 minutes. The log file is found in \probes\network\pollagent. Pollagent now reads startup parameters in a pollagent.cfg file. This file allows the startup options to remain in place during an upgrade. The file is found in \probes\network\pollagent.
• The probe now performs license checks.
• Simplified the probe configuration by removing the configuration for custom monitors.
• Hardened concurrency guard to snmpcollector configuration and component files.
• Hardened pollagent behavior during a timeout and the sysUptime query fails.
• Re-architected TaskController to prevent race conditions during data read/write.
• Throttled back aggressive discovery/rediscovery behavior to only process requested devices in the rediscovery callback.
• DevIDs no longer change to GUIDs.
• Setting the discovery time to 0 no longer causes discovery to go into an infinite loop. A setting of 0 inactivates discovery.
• Corrected an issue with unpredictable component configuration file behavior for unreachable devices.
• Corrected an issue where an index shift would cause the probe to stop publishing QoS data for the device.
• Corrected an issue with device rediscovery where the probe would drop existing polled metrics when new components, properties, or metrics are added to an existing device.
• Corrected an issue where pollagent intermittently stops polling with no errors or obvious reason.
• Updated metrics for:
• Checkpoint Firewall memory reserved
• InfoBlox DHCP metrics
• Firewall VSX Chassis memory reserved
• Bluecoat CPU utilization
• Checkpoint traffic metrics
• Checkpoint memory metrics
• Juniper netscreen total connections
• Bluecoat proxy cpu utilization
• F5 connection metrics
• Nexus 7k number or port channels active
• RPF Poxy load average
• McAfee CPU utilization
• Added special logging and fixes for delta values of 0
• Attempt to work around bluecoat bad net-snmp agent.
• Fixes bad max value for counter32 rolls.

• The Component User Defined Property field now persists with rediscovery.
• IP addresses that were incorrectly appearing in hex now appear as IP addresses.
• Corrected issues with metric families causing device discovery to poll too many OIDs.
• Corrected issues where changes to metric families were causing template upgrades to fail.
• Corrected an issue where agent restarts would cause the probe to incorrectly calculate metrics with delta values.

• The custom properties on device profiles now appear correctly in the probe configuration GUI.
• The default templates are now read-only and inactive. Activate these templates through the template editor to apply the default metric settings to your devices.

• Added the ability for users to define their own custom properties
on device profiles. Use these properties to further refine the
rules for applying a template filter.
• Converted metrics from polled to nonpolled so they no longer
appear incorrectly in monitoring templates.
o ManagementRedundancyRole and LastRestartReason
in the Server Statistics metric family
o SourceIpPort, DestinationIpPort, IpProtocol, EtherType,
and MediaRingType in the System Ip Policer metric
family
o PolId and PolPriority in the Acl Stats metric family

-Added the ability to set a fixed time for data collection within the polling
interval. The RandomFixedSchedule configuration option is in the pollagent fh.
conf file (\probes\network\pollagent\conf). The default probe
behavior is to collect data at a random point within the interval.
-The probe now publishes data in USM by host name. Previously, the default
behavior was to publish data by IP address. You can disable this behavior in
the probe Raw Configure setup options.
-The device Availability metric allows you to determine if the device was
available within a polling interval. The metric value is 100% if the device was
operating the entire time since last polling cycle, or 0% if the device stopped
operating for some period of time since the last polling cycle. This corrects the
known issue, "The Availability metric value is either 100 or No Value (null)".
-Corrected an issue with deprecated metric families that was causing template
migrations from v2.0 to v2.1 to fail.
-Updated metrics in the following metric families:
-DNS metric family has the CacheHitRatio metric
-System Session Information metric family has the SessionRate1Min metric
-License Management metric family contains the TotalLicenses and UsedLicenses metrics
-Updated memory and disk requirements for v2.1 snmpcollector and pollagent.
