PerfTcpIp-Check

Checks packets and CRC errors on the TCP/IP stack.

Usage

$ check_netapp_pro.pl PerfTcpIp -H <host> -o ip|tcp -z recv_bad_checksum|recv_packets|sent_packets ... [--help] [...]

Description

This plugin checks some performance- and error- counters for the TCP/IP protocol.

Only supported on cluster-mode filers.

Hint: Calling the getter with the switch --discover=counters will explain each available counter in detail.

Simple Examples

[S1] ./check_netapp_pro.pl PerfTcpIp -H filer -o ip -z recv_bad_checksum

Checks for crc-errors on the IP level.

NETAPP_PRO PERFTCPIP OK - 2 ips checked
ip (cluster1-01:kernel:ip): 0.0/s recv_bad_checksum
ip (cluster1-02:kernel:ip): 0.0/s recv_bad_checksum
 | ip=0/s;80;90;0; ip=0/s;80;90;0;

[S2] ./check_netapp_pro.pl PerfTcpIp -H filer -o tcp -z recv_bad_checksum

Checks for crc-errors on the TCP level.

NETAPP_PRO PERFTCPIP OK - 2 tcps checked
tcp (cluster1-01:kernel:tcp): 0.0/s recv_bad_checksum
tcp (cluster1-02:kernel:tcp): 0.0/s recv_bad_checksum
 | tcp=0/s;80;90;0; tcp=0/s;80;90;0;
