ESXi VMware ESXTOP
-
I'm hoping someone can help me out here. I've trying to write the output of ESXTOP (Device Average Latency) to a csv file.
The will output to STOUT through putty, but I can't figure out how to write it to a file for review.
esxtop <enter> d Shift+L 36 <enter> f b,c,d,e,h,j <enter> s 2 <enter>That will update the shell session every 2 seconds and provide the Device average latency, but how can I get this output to write out like
>>so I can review it without having to monitor it "live" -
Is there any command option available? I know
tophas an option you can feed it that makes it function in such a way that you can easily send the data to a file. -
@eddiejennings there is, but only when you aren't passing any options to it.
esxtop >> /logvile.csvfor example would just dump everything from the tool. I specifically want to filter down to just the device latency. -

>>so I can review it without having to monitor it "live"For example:
[root@localhost:~] esxtop
The above command will open the interactive screen of esxtop, by default.[root@localhost:~] esxtop -b -a -d 10 -n 3 > /vmfs/volumes/localhost/test.csv
The above command runs the batch mode of esxtop with all counters, updates delay of 10 secs for 3 iterations. The output is written to the test.csv file which can be opened with other tools like Windows Perfmon. -
@pete-s Yeah I saw that, but this won't output just the specific detail I'm looking for. It will output everything (and essentially bloat the logs).
I saw the same thing.
Thanks though

Make the script a two step process until you can figure it out.
- Dump it all to CSV.
- Then have the script remove unneeded data from CSV.

Or just pipe the output to grep, awk or whatever before writing it to file.
The batch mode of esxtop at least will let give you the information without having to do it interactively. -

@obsolesce awk is surprisingly simple to use. Easiest text processor that I know.
-
Why not just use PowerShell?
-
Does the esxi shell have awk?
-
@stacksofplates it might, I'll have to double-check next week

How would I use powershell when I'm ssh'd into the host?
I get that I can use powershell to pull details from the host, but that's a different approach than what I'm doing
