PerfSys-Check

Checks operations/second, transfer rates and several cpu-related counters.

Usage

$ check_netapp_pro.pl PerfSys -H <host> -z http_ops|cifs_ops|net_data_sent|... -w <n> -c <n> [--help] [...]

Description

This plugin checks various performance counters of the NetApp-system.

A list of supported counters is printed via the --counter switch.

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

Simple Examples

[S1] ./check_netapp_pro.pl PerfSys -H filer --explore=counters

List all available counters on the target system.

Counters (unit) supported by system:
 avg_processor_busy (%)
 cifs_ops (/s)
 cpu_busy (%)
 cpu_elapsed_time ()
 cpu_elapsed_time1 ()
 cpu_elapsed_time2 ()
 disk_data_read (kiB/s)
 disk_data_written (kiB/s)
 fcp_ops (/s)
 http_ops (/s)
 instance_name ()
 instance_uuid ()
 iscsi_ops (/s)
 net_data_recv (kiB/s)
 net_data_sent (kiB/s)
 nfs_ops (/s)
 node_name ()
 total_ops (/s)
 total_processor_busy (%)

[S2] ./check_netapp_pro.pl PerfSys -H filer -z cpu_busy

Checks the system CPU resource utilization

NETAPP_PRO PERFSYS OK - 2 systems checked.
system (cluster1-02:kernel:system): 1.7% cpu_busy
system (cluster1-01:kernel:system): 1.4% cpu_busy
 | system=1%;80;90;0;100 system=2%;80;90;0;100

[S3] ./check_netapp_pro.pl PerfSys -H filer -z total_ops

Checks the systems total operations per second

NETAPP_PRO PERFSYS OK - 2 systems checked.
system (cluster1-01:kernel:system): 204.0/s total_ops
system (cluster1-02:kernel:system): 123.4/s total_ops
 | system=204/s;80;90;0; system=123/s;80;90;0;

[S4] ./check_netapp_pro.pl PerfSys -H filer -z http_ops -w 2000/s -c 3000/s

Check the http-operations per second - warn if rate is greater than 2000 operations per second, exit critical if rate is greater than 3000.

[S5] ./check_netapp_pro.pl PerfSys -H filer -z nfs_ops -w 2000/s -c 3000/s

Same as above, but for nfs-operations.

[S6] ./check_netapp_pro.pl PerfSys -H filer -z net_data_sent -w 1024kiB/s -c 4096kiB/s

Check the transfer rate (kilo bytes/second send to the network). Warn if transfer rate exceeds 1 MByte/s ... .
