# Monitoring Compression

To monitor card performance, right-click the card and select Monitor from the popup menu. The CiscoView Monitor Card window appears.

The CiscoView Monitor Card window displays the following for a CSA card:

Compressed Octets Received (In Octets)

Compressed Octets Sent (Out Octets)

Compressed Packets Received (In Packets)

Compressed Packets Sent (Out Packets)

Input Packets Dropped

Output Packets Dropped

Number of Restarts

Compression Ratio

Decompression Ratio

Compressed Octets Received (csaInOctets)

Total number of compressed octets received by the CSA.

Compressed Octets Sent (csaOutOctets)

Total number of compressed octets sent by the CSA.

Compressed Packets Received (csaInPackets)

Number of compressed packets received by the CSA.

Compressed Packets Sent (csaOutPackets)

Number of compressed packets sent by the CSA.

Input Packets Dropped (csaInPacketsDrop)

Number of input packets dropped. A large value indicates that too much data is being passed to the CSA for it to process.

Output Packets Dropped (csaOutPacketsDrop)

Number of output packets dropped. A large value indicates that too much data is being passed to the CSA for it to process.

Number of Restarts (csaNumberOfRestarts)

Number of compression session restarts. A large value indicates one or more of the following:

Remote router is incompatible.

Data is being corrupted in transmission.

Packet order is not being maintained.

Compression Ratio (csaCompressionRatio)

The current compression ratio, expressed as the percentage by which the data just processed was compressed. A compression ratio of 0% indicates no compression; a compression ratio of 90% indicates compression to 1/10 the size of the uncompressed input data (e.g. 100 octets were compressed to 10 octets).

Decompression Ratio (csaDecompressionRatio)

The current decompression ratio, expressed as the percentage by which the data just processed was decompressed. A decompression ratio of 0% indicates no decompression; a decompression ratio of 90% indicates decompression to 10 times the size of the compressed input data (e.g. 10 octets were decompressed to 100 octets).
