Exchange RPC Average Latency Is High
    AIS Monitoring Platform has discovered high RPC Average Latency on exchange server. The RPC Averaged Latency performance counter records the average time, in milliseconds (ms), that it takes for the last 1024 packets to be processed. The latency represents how long it takes from the time the Store.exe process received the packet to the time it returned the packet. Although the RPC Averaged Latency performance counter data does not include network transit time, it does provide data about the shortest time period that client computers have waited for a response from the server. If the counter stays greater than 50 ms for more than several seconds, this indicates that the server is having difficulty keeping up with the load. As a result, users may experience delays when accessing their e-mail.
Exchange Server Number Of Free Page Table Entries Is Low Which Can Cause System Instability
    This alert condition indicates that the system is low on Page Table Entries. Microsoft Windows Server 2003 and Windows 2000 Server can directly address up to 4 gigabytes (GB) of memory address space, regardless of how much physical RAM is installed. From the process perspective, each element of virtual address conceptually refers to a byte of physical memory. It is the responsibility of the Virtual Memory Manager (VMM) (in conjunction with the processor memory management unit (MMU)) to translate or map each virtual address into a corresponding physical address. The VMM performs the mapping by dividing the RAM into fixed-size page frames, creating system PTEs to store information about these page frames, and mapping them. System PTEs are small kernel-mode buffers of memory that are used to communicate with the disk I/O sub-system and the network. Each PTE represents a page frame and contains information necessary for the VMM to locate a page.
Exchange Store Named Property Issue For Database
    AIS Monitoring Platform has discovered Exchange Store named property issue for Database. In an Exchange Server 2007 environment, a named property that is used to map X-headers during a message is processed at the mailbox store level. However, the named property has a size restriction. When many X-headers are promoted to named properties and the quota limitation is reached, unexpected problems occur.
Exchange Suspected Memory Leak Found
    AIS Monitoring Platform has discovered suspected Memory Leak issue on exchange server. This indicates that the Exchange Server is running out of Nonpaged pool Memory, due to which the users may face performance issues. As a workaround you may try restarting the server.
Exchange Transaction Log Sequence Numbers For Exchange Instance Have Almost Been Completely Consumed
    This Error event indicates that there are approximately 131,000 log file names remaining. The maximum number of transaction log files that can be generated in a single sequence is 2,147,486,647 (0x7FFFFFFF). Typically, it will take dozens to hundreds of years of operation before this many log files will be generated. You can calculate how long it will take you to exhaust the remaining logs by determining how many logs are generated on a typical day and then dividing 131,000 by that number for an approximate number of days remaining. This calculation will be a very rough estimate and is only valid the first time the event occurs. However, you should immediately schedule a maintenance window where you can resolve the problem and prevent the storage group from disconnecting on its own when the available log file names are exhausted.
Exchange VM Largest Block Size Is Low
    This alert condition indicates that the Exchange VM Largest Block Size is low. This size is determined when AIS Monitoring agent queries the Active Directory directory service to determine the mailbox count for each mailbox store. The count of this attribute represents the number of mailboxes on the mailbox store. If the query finds the value for the VMLargestBlockSize is greater than 0 but less than 50000001 on an Exchange Server computer with more than 20 mailboxes, this error message is displayed. Among other things, Exchange Server uses virtual memory to store messages when you convert them between MIME and MAPI formats, and as a buffer when committing messages from the transaction log and committing to the store. Frequently, these operations require large contiguous chunks of virtual memory to complete quickly and efficiently. If this warning has been displayed, the virtual memory on the Exchange computer is depleted to less than 150 MB of contiguous space. This is known as virtual memory fragmentation. If the virtual memory depletes too much, you may start to see error messages in the event log (Event ID 9582), which are virtual memory errors. If virtual memory is low enough, you will see Event ID 12800, which indicates that messages are not being delivered because there is insufficient memory to process them.
Heavier Than Normal Load And That An Increase In RPC Latencies
    AIS Monitoring Platform has discovered that the exchange server is experiencing heavier than normal load and that an increase in RPC latencies or RPC thread exhaustion. This issue can manifest itself as mail clients experiencing slowdowns or by the appearance of the Cancel Request dialog box.
HIGH Exchange RPC Averaged Latency On Exchange 2007
    AIS Monitoring Platform has discovered that the RPC averaged latency is high on exchange server. The RPC Averaged Latency counter displays the average time that it takes the server to respond to client requests. The value of the counter is typically less than 50 milliseconds in typical operations. If the value is consistently more than 50 milliseconds with Outlook client when most of the users are in Online Mode, this means that the Information Store is taking a long time to process user requests. If most Outlook users are in Cached Mode, this threshold increases to 100 milliseconds. Typically, if the Information Store is taking a long time, there is a disk bottleneck. Users will experience performance problems.
High MAPI Requests Being Serviced By The Microsoft Exchange Information Store Service
    AIS Monitoring Platform has discovered High MAPI requests being serviced by the Microsoft Exchange Information Store service. When using Microsoft Office Outlook in MAPI mode, clients actions in Outlook translate to remote procedure calls (RPCs) between the clients and the server. If the user is running in online mode, these
