| Log Generation Checkpoint Depth | Indicates that the Exchange server is receiving messages faster than they it can written to the transport queue database due to reduced flow of intra-site, inter-site, or external mail messages. This may be due to message volume exceeding server capacity, applications other than Microsoft Exchange Server are accessing or placing file locks on the transaction log files, or hard disks are not performing at a level to meet the disk I/O requirements of the Exchange environment. |
| IO Database Reads Average Latency | Indicates the average time, in milliseconds (ms), to read from the database file. |
| IO Database Writes Average Latency | Indicates the average time, in milliseconds (ms), to write to the database file. |
