•  PFS and RSP enabled together - It updates every five minutes.

•  Time drift - It updates every five minutes.

•  Too Many Half Open/Closed Connections - It updates every 30 seconds.

•  Unmanaged Appliances - It updates every 3 hours.

•  Connection Limit - Indicates the system connection limit has been reached. Additional connections are passed through unoptimized. The alarm clears when the appliance moves out of this condition.

•  CPU - The appliance has entered admission control due to high CPU use. During this event, the appliance continues to optimize existing connections, but new connections are passed through without optimization. The alarm clears automatically when the CPU usage has decreased.

•  MAPI - The total number of MAPI optimized connections have exceeded the maximum admission control threshold. By default, the maximum admission control threshold is 85 percent of the total maximum optimized connection count for the client-side appliance. The appliance reserves the remaining 15 percent so that the MAPI admission control does not affect the other protocols. The 85 percent threshold is applied only to MAPI connections. RiOS is now passing through MAPI connections from new clients but continues to intercept and optimize MAPI connections from existing clients (including new MAPI connections from these clients). RiOS continues optimizing non-MAPI connections from all clients. The alarm clears automatically when the MAPI traffic has decreased; however, it can take one minute for the alarm to clear.

•  Memory - The appliance has entered admission control due to memory consumption. The appliance is optimizing traffic beyond its rated capability and is unable to handle the amount of traffic passing through the WAN link. During this event, the appliance continues to optimize existing connections, but new connections are passed through without optimization. No other action is necessary; the alarm clears automatically when the traffic has decreased.

•  TCP - The appliance has entered admission control due to high TCP memory use. During this event, the appliance continues to optimize existing connections, but new connections are passed through without optimization. The alarm clears automatically when the TCP memory pressure has decreased.

•  Cluster IPv6 Incompatible - Enables an alarm and sends an email notification if a connection-forwarding neighbor is running a RiOS version that is incompatible with IPv6, or if the IP address configuration between neighbors does not match. Neighbors must be running RiOS 8.5.

•  Multiple Interface - Enables an alarm and sends an email notification if the connection to an appliance in a connection forwarding cluster is lost.

•  Single Interface - Enables an alarm and sends an email notification if the connection to a SteelHead connection forwarding neighbor is lost.

•  Rising Threshold - Specify the rising threshold. When an alarm reaches the rising threshold, it is activated. The default value is 90 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 is not triggered again until it has fallen below the reset threshold. The default value is 70 percent.

•  Data Store Clean Required - Enables an alarm and sends an email notification if you need to clear the RiOS data store.

•  Corruption - Enables an alarm and sends an email notification if the RiOS data store is corrupt or has become incompatible with the current configuration. To clear the RiOS data store of data, restart the optimization service and click Clear the Data Store.

•  Encryption Level Mismatch - Enables an alarm and sends an email notification if a data store error such as an encryption, header, or format error occurs.

•  Synchronization Error - Enables an alarm if RiOS data store synchronization has failed. The RiOS data store synchronization between two SteelHeads has been disrupted and the RiOS data stores are no longer synchronized.

•  Disk Error - Enables an alarm when one or more disks is offline. To see that disk is offline, enter the following CLI command from the system prompt:

•  Fan Error - Enables an alarm and sends an email notification if a fan is failing or has failed and needs to be replaced. By default, this alarm is enabled.

•  Flash Error - Enables an alarm when the system detects an error with the flash drive hardware. By default, this alarm is enabled.

•  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.)

•  Memory Error - Enables an alarm and sends an email notification if a memory error is detected. For example, when a system memory stick fails.

•  Other Hardware Error - Enables an alarm if a hardware error is detected. These issues trigger the hardware error alarm:

•  Power Supply - Enables an alarm and sends an email notification if an inserted power supply cord does not have power, as opposed to a power supply slot with no power supply cord inserted. By default, this alarm is enabled.

•  RAID - Enables an alarm and sends an email notification if the system encounters an error with the RAID array (for example, missing drives, pulled drives, drive failures, and drive rebuilds). An audible alarm can also sound. To see if a disk has failed, enter the following CLI command from the system prompt:

•  SSD Write Cycle Level Exceeded - Enables an alarm if the accumulated SSD write cycles exceed a predefined write cycle 95 percent level on appliance models 7050L and 7050M. If the alarm is triggered, the administrator can swap out the disk before any problems arise. For details, see the Riverbed Command-Line Interface Reference Manual.

•  Appliance Unlicensed - This alarm triggers if the appliance has no BASE or MSPEC license installed for its currently configured model.

•  Autolicense Critical Event - This alarm triggers on a SteelHead (virtual edition) when the Riverbed Licensing Portal cannot response to a license request with valid licenses. The Licensing Portal cannot issue a valid license for one of these reasons:

•  Autolicense Informational Event - This alarm triggers if the Riverbed Licensing Portal has information regarding the licenses for a SteelHead (virtual edition). For example, the SteelHead (virtual edition) displays this alarm when the portal returns licenses that are associated with a token that has been used on a different SteelHead (virtual edition).

•  Licenses Expired - This alarm triggers if one or more features has at least one license installed, but all of them are expired.

•  Licenses Expiring - This alarm triggers if the license for one or more features is going to expire within two weeks.

•  Internal Error - Enables an alarm and sends an email notification if the RiOS optimization service encounters a condition that can degrade optimization performance. By default, this alarm is enabled.

•  Service Status - Enables an alarm and sends an email notification if the RiOS optimization service encounters a service condition. By default, this alarm is enabled. The message indicates the reason for the condition. These conditions trigger this alarm:

•  Unexpected Halt - Enables an alarm and sends an email notification if the RiOS optimization service halts due to a serious software error. By default, this alarm is enabled.

•  Proxy File Service Configuration - Indicates that a configuration attempt has failed. If the system detects a configuration failure, attempt the configuration again.

•  Proxy File Service Operation - Indicates that a synchronization operation has failed. If the system detects an operation failure, attempt the operation again.

•  Proxy File Service Configuration - Indicates that a configuration attempt has failed. If the system detects a configuration failure, attempt the configuration again.

•  Proxy File Service Operation - Indicates that a synchronization operation has failed. If the system detects an operation failure, attempt the operation again.

•  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. Choose Appliance > Secure Vault and unlock the secure vault.

•  Secure Vault New Password Recommended - Indicates that the secure vault requires a new, nondefault password. Reenter the password.

•  Secure Vault Not Initialized - Indicates that an error has occurred while initializing the secure vault. When the vault is locked, SSL traffic is not optimized and you cannot encrypt the RiOS data store.

•  Peer Mismatch - Needs Attention - Indicates that the appliance has encountered another appliance that is running an incompatible version of system software. Refer to the CLI, SteelCentral Controller for SteelHead, or the SNMP peer table to determine that appliance is causing the conflict. Connections with that peer will not be optimized, connections with other peers running compatible RiOS versions are unaffected. To resolve the problem, upgrade your system software. No other action is required as the alarm clears automatically.

•  Software Version Mismatch - Degraded - Indicates that the appliance is running an incompatible version of system software. To resolve the problem, upgrade your system software. No other action is required as the alarm clears automatically.

•  Non-443 SSL Servers - Indicates that during a RiOS upgrade (for example, from 5.5 to 6.0), the system has detected a preexisting SSL server certificate configuration on a port other than the default SSL port 443. SSL traffic cannot be optimized. To restore SSL optimization, you can add an in-path rule to the client-side appliance to intercept the connection and optimize the SSL traffic on the nondefault SSL server port.

•  SSL Certificates Error (SSL CAs) - Indicates that an SSL peering certificate has failed to reenroll automatically within the Simple Certificate Enrollment Protocol (SCEP) polling interval.

•  SSL Certificates Error (SSL Peering CAs) - Indicates that an SSL peering certificate has failed to reenroll automatically within the Simple Certificate Enrollment Protocol (SCEP) polling interval.
