Chapter 5 Cisco Unified Real-Time Monitoring Tool Tracing, PerfMon Counters, and Alerts Performance Monitoring in RTMT Table 5-51 Counters Pages Input Memory (continued) Pages Input Per Sec Pages Output Pages Output Per Sec Shared KBytes Total KBytes Total Swap KBytes Total VM KBytes Used KBytes Used Swap KBytes Used VM KBytes Counter Descriptions This counter represents the number of pages that the system paged in from the disk. This counter represents the total number of kilobytes that the system paged in from the disk per second. This counter represents the number of pages that the system paged out to the disk. This counter represents the total number of kilobytes that the system paged out to the disk per second. This counter represents the amount of shared memory in your system in kilobytes. This counter represents the total amount of memory in your system in kilobytes. This counter represents the total amount of swap space in your system in kilobytes. This counter represents the total amount of system physical and memory and swap space (Total Kbytes + Total Swap Kbytes) that is in use in your system in kilobytes. This counter represents the amount of system physical memory that is in use in kilobytes. The value of the Used KBytes counter equals Total KBytes minus Free KBytes minus Buffers KBytes minus Cached KBytes plus Shared KBytes. In a Linux environment, the Used KBytes value that displays in the top or free command output equals the difference of Total KBytes and Free KBytes and also includes the sum of Buffers KBytes and Cached KBytes. This counter represents the amount of swap space that is in use on your system in kilobytes. This counter represents the system physical memory and the amount of swap space that is in use on your system in kilobytes. The value equals Total KBytes Free KBytes - Buffers KBytes - Cached KBytes + Shared KBytes + Used Swap KBytes. This corresponds to Used Mem KBytes + Used Swap KBytes. Network Interface The network interface object provides information about the network interfaces on the system. Table 5-52 contains information on network interface counters. Table 5-52 Network Interface Counters Rx Bytes Rx Dropped Counter Descriptions This counter represents the number of bytes, including framing characters, that were received on the interface. This counter represents the number of inbound packets that were chosen to be discarded even though no errors had been detected. This prevents the packet from being delivered to a higher layer protocol. Discarding packets to free up buffer space provides one reason.
