This page provides details on monitoring Google Cloud NetApp Volumes performance.
Use Cloud Monitoring to track volume performance statistics
Cloud Monitoring tracks multiple performance
metrics per volume that let you observe current and short-lived performance
events. Metrics update every five minutes and provide an overview of performance
trends, for periods of one day or longer, see NetApp Volumes Cloud Monitoring metrics.
Collect NFS performance statistics on your Linux operating system
You can collect Network File System (NFS) performance statistics on your Linux
operating system using the following statistics:
nfsiostat: provides IOPS (ops/s), throughput (kB/s), blocksize
(kB/op), and latency (average round-trip time (ms)) metrics. The
information is split into read and write per NFS mount and is used to monitor
traffic in real time.
mountstats: provides details about each NFS mount by NFS operation
type. Each operation type shows the number of requests, the average number of
transferred bytes, and the average latency.
nfsstat: provides details on how often NFS operations are called.
This statistic can be used to determine the read and write ratio of your
workload and helps to determine how metadata-intensive
(metadata operations versus read and write) it is.
If your Linux installation doesn't provide these tools, consult your
distributions package management system to determine which package provides
them. For Debian-based systems like Ubuntu, they are provided in nfs-common.
The Performance Monitor application and command line can be used to access the
metrics, show real-time graphs, and collect data to create reports. For more
information, see perfmon.
You can map a network share to see performance metrics like IOPS and latency.
Server Message Block (SMB) metrics are found under SMB Client Shares and
metrics are available for every mapped share.
The following table shows the NetApp Volumes metrics and their
corresponding names in the Windows Performance Monitor.
Metric
SMB client shares performance monitor name
Block size
Average data bytes per request
Latency
Average seconds per data request. Use scale 1,000 for milliseconds
IOPS
Data requests per second
Throughput
Data bytes per second
Concurrency
Average data queue length and current data queue length
Read and write ratio
Read bytes per second versus write bytes per second
Non-read and write requests, like listing a directory, reading file
attributes, and deleting files
