NVRAM-Check
Checks data-rates and latency of the NVRAM.
Usage
$ check_netapp_pro.pl NVRAM -H <host> [-z total_nvlog_data|...] [--help] [...]
Description
This plugin checks various NVRAM performance counters of the NetApp-system like:
write_data => NVRAM data in bytes written per second
total_nvlog_data => Total nvlog bytes per second
transaction_count => NVRAM DMA transactions per second
dma_wait_latency => NVRAM DMA wait time per transaction
total_dma_data => NVRAM data in bytes DMAed per second
nvlog_header_array_full => NVLOG shadow header full count
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
Simple Examples
[S1] ./check_netapp_pro.pl NVRAM -H filer --explore=counters
List all available and supported counters on the target system.
[S2] ./check_netapp_pro.pl NVRAM -H filer -z write_data -w 200000 -c 300000
Check the data-rate being written to the NVRAM. Warn if more than 200KB per second are transfered.
[S3] ./check_netapp_pro.pl NVRAM -H filer -z dma_wait_latency -w 0.1 -c 0.4
Check the wait-time per transaction. Warn if it exceeds 100 ms.
