Performance Monitoring in RTMT Chapter 5 Cisco Unified Real-Time Monitoring Tool Tracing, PerfMon Counters, and Alerts Table 5-50 Counters Reasm Fails IP (continued) Reasm OKs Reasm Reqds Counter Descriptions This counter represents the number of IP reassembly failures that the IP reassembly algorithm detected, including time outs, errors, and so on. This counter does not represent the discarded IP fragments because some algorithms, such as the algorithm in RFC 815, can lose track of the number of fragments because it combines them as they are received. This counter represents the number of IP datagrams that were successfully reassembled. This counter represents the number of IP fragments that were received that required reassembly at this entity. Memory The memory object provides information about the usage of physical memory and swap memory on the server. Table 5-51 contains information on memory counters. Table 5-51 Memory Counters % Mem Used % Page Usage % VM Used Buffers KBytes Cached KBytes Free KBytes Free Swap KBytes Faults Per Sec Low Total Low Free Major Faults Per Sec Pages Counter Descriptions This counter displays the system physical memory utilization as a percentage. The value of this counter equals (Total KBytes - Free KBytes - Buffers KBytes Cached KBytes + Shared KBytes) / Total KBytes, which also corresponds to the Used KBytes/Total KBytes. This counter represents the percentage of active pages. This counter displays the system virtual memory utilization as a percentage. The value of this counter equals (Total KBytes - Free KBytes - Buffers KBytes Cached KBytes + Shared KBytes + Used Swap KBytes) / (Total KBytes + Total Swap KBytes), which also corresponds to Used VM KBytes/Total VM KBytes. This counter represents the capacity of buffers in your system in kilobytes. This counter represents the amount of cached memory in kilobytes. This counter represents the total amount of memory that is available in your system in kilobytes. This counter represents the amount of free swap space that is available in your system in kilobytes. This counter represents the number of page faults (both major and minor) that the system made per second (post 2.5 kernels only). This does not necessarily represent a count of page faults that generate I/O because some page faults can get resolved without I/O. This counter represents the total low (non-paged) memory for kernel. This counter represents the total free low (non-paged) memory for kernel. This counter represents the number of major faults that the system has made per second that have required loading a memory page from disk (post 2.5 kernels only). This counter represents the number of pages that the system paged in from the disk plus the number of pages that the system paged out to the disk. 5-66 Cisco Unified Communications Manager Managed Services Guide OL-22523-01
