Configuring alarm parameters
You configure alarm parameters under Administration > System Settings: Alarms.
These configuration options are available under Enable SCC Alarms:
CPU Utilization
Enables an alarm if the average and peak threshold for the CPU utilization is exceeded. When an alarm reaches the rising threshold, it is activated; when it reaches the lowest or reset threshold, it is reset. After an alarm is triggered, it isn’t triggered again until it has fallen below the reset threshold. By default, this alarm is enabled, with a rising threshold of 90 percent and a reset threshold of 70 percent.
• Rising Threshold—Specify the rising threshold. When an alarm reaches the rising threshold, it is activated. The default value is 70 percent.
• Reset Threshold—Specify the reset threshold. When an alarm reaches the lowest or reset threshold, it is reset. After an alarm is triggered, it isn’t triggered again until it has fallen below the reset threshold. The default value is 70 percent.
Disk Full
Enables an alarm if the system partitions (not the RiOS data store) are full or almost full. For example, RiOS monitors the available space on /var, which is used to hold logs, statistics, system dumps, TCP dumps, and so on. By default, this alarm is enabled. This alarm monitors these system partitions:
• Partition "/boot Full" Free Space
• Partition "/bootmgr Full" Free Space
• Partition "/config Full" Free Space
• Partition "/data Full" Free Space
• Partition "/proxy Full" Free Space
• Partition "/var Full" Free Space
Hardware Flash Error
Enables an alarm when the system detects an error with the flash drive hardware. By default, this alarm is enabled.
Hardware IPMI
Enables an alarm and sends an email notification if an Intelligent Platform Management Interface (IPMI) event is detected (not supported on all appliance models). By default, this alarm is enabled. This alarm triggers when there has been a physical security intrusion. These events trigger this alarm:
• Chassis intrusion (physical opening and closing of the appliance case)
• Memory errors (correctable or uncorrectable ECC memory errors)
• Hard drive faults or predictive failures
• Power supply status or predictive failures
Licensing
Enables an alarm and sends an email notification if a license on the SCC is removed, is about to expire, has expired, or is invalid. This alarm triggers if the SCC has no MSPEC license installed for its currently configured model. By default, this alarm is enabled.
• Autolicense critical event—This alarm triggers on an appliance when the Riverbed Licensing Portal can’t respond to a license request with valid licenses.
• Autolicense information event—This alarm triggers if an information event for autolicense occurs, such as when the portal returns licenses that are associated with a token that has been used on a different appliance.
• Insufficient Appliance Management License(s)—This alarm triggers if the SCC has insufficient license(s).
• Invalid License(s)—This alarm triggers if one or more licenses are invalid.
• License(s) Expired—This alarm triggers if one or more features have at least one license installed, but all of them are expired.
• License(s) Expiring—This alarm triggers if the license for one or more features is going to expire within two weeks.
• License(s) Missing—This alarm triggers if one or more licenses are missing.
The licenses expiring and licenses expired alarms are triggered per feature. For example, if you install two license keys for a feature, LK1-FOO-xxx (expired) and LK1-FOO-yyy (not expired), the alarms don’t trigger, because the feature has one valid license.
Link Duplex
Enables an alarm and sends an email notification when an interface wasn’t configured for half-duplex negotiation but has negotiated half-duplex mode. By default, this alarm is enabled. Half-duplex significantly limits the optimization service results. The alarm displays which interface is triggering the duplex alarm.
• Interface aux Half-Duplex—Select to enable an alarm on this interface.
• Interface primary Errors—Select to enable an alarm on this interface.
Link I/O Errors
Enables an alarm and sends an email notification when the link error rate exceeds 0.1 percent while either sending or receiving packets. This threshold is based on the observation that even a small link error rate reduces TCP throughput significantly. A properly configured LAN connection experiences very few errors. By default, this alarm is enabled.
• Interface aux Half-Duplex—Select to enable an alarm on this interface.
• Interface primary Errors—Select to enable an alarm on this interface.
The alarm clears when the rate drops below 0.05 percent.
You can change the default alarm thresholds by entering the alarm linkers threshold xxxxx CLI command at the system prompt. For details, see the Riverbed Command-Line Interface Reference Manual.
Link State
Enables an alarm and sends an email notification if an Ethernet link is lost due to a network event. Depending on that link is down, the system can no longer be optimizing and a network outage could occur. By default, this alarm is disabled.
• Interface aux Down—Select to enable an alarm on this interface.
• Interface primary Down—Select to enable an alarm on this interface.
This alarm is often caused by surrounding devices, like routers or switches, interface transitioning. It also accompanies service or system restarts on the appliance. For WAN/LAN interfaces, the alarm triggers if in-path support is enabled for that WAN/LAN pair.
Memory Paging
Enables the memory paging alarm. If 100 pages are swapped every couple of hours, the system is
functioning properly. If thousands of pages are swapped every few minutes, contact Support at https://support.riverbed.com. By default, this alarm is enabled.
Process Dump Creation Error
Enables an alarm that indicates that the system has detected an error while trying to create a process
dump. To correct the issue, contact Support at https://support.riverbed.com.
SCC Appliance Configuration Backup
Enables an alarm when an SCC configuration backup occurs.
SCC External Configuration Backup/Restore
Enables an alarm when an SCC external configuration backup and restore failure occurs.
SCC External Statistics Backup/Restore
Enables an alarm when an SCC statistics backup and restore failure occurs.
SCC Under Provisioned Virtual Machine
Enables an alarm that indicates when a virtual machine is under provisioned.
Secure Vault
Enables an alarm and sends an email notification if the system encounters a problem with the secure vault.
• Secure Vault Locked indicates that the secure vault is locked. To optimize SSL connections or to use RiOS data store encryption, the secure vault must be unlocked.
SSL
Enables an alarm if an error is detected in your SSL configuration. By default, this alarm is enabled.
These configuration options are available under CMC Managed Appliance Alarms:
Appliance too slow to respond
Enables an alarm when the appliance is too slow to respond. By default, this alarm is enabled.
Configuration Change
Enables an alarm when a configuration change is detected. By default, this alarm is disabled.
Duplex Interface
Enables an alarm when the appliance duplex interface is detected. You can enable the alarm on the following interfaces, only the Interface aux Duplex State is enabled by default:
• Interface aux Duplex State
• Interface lan0_0 Duplex State
• Interface primary Duplex State
• Interface wan0_0 Duplex State
High Appliance Usage Warning
Enables an alarm when high appliance usage is detected. By default, this alarm is enabled.
Connection Limit Warning
Enables an alarm when a connection limit is detected.
PFS and RSP enabled together
Enables an alarm when PFS and RSP are enabled together. By default, this alarm is enabled.
Time drift
Enables an alarm when time drift is detected. By default, this alarm is enabled.
Too Many Half Open/Closed Connections
Enables an alarm when too many half-opened or half-closed connections are active. By default, this alarm is enabled.
Unmanaged Appliances
Allows you to set these alarms for unmanaged appliances:
• Add Unmanaged Peer Exceptions—Select to enable an alarm when the SCC detects unmanaged peers.
• Ignore Peer—Select to enable an alarm when a peer is ignored.
• Comment—Optionally, specify a comment.
