Data not showing in dashboards for cisco mds

[protoss1232001]

I have multiple influx DB's on my instance. Where do I specify the db name for the script to write to?

[paregupt]

db name is specified in the grafana dashboard variable. $db and $rp

[protoss1232001]

While importing the DB in grafana I selected the appropriate db.

Does it have to be specified in any of these files also? /usr/local/telegraf/grafana/dashboards#ls -l total 828 -rw------- 1 root root 38378 Jun 18 11:43 local_sys.json -rw------- 1 root root 233926 Jun 18 11:43 locations.json -rw------- 1 root root 233926 Jun 18 17:42 locations.json.old -rw------- 1 root root 244204 Jun 18 11:43 switches.json -rw------- 1 root root 84405 Jun 18 11:43 switchports.json

Yes, the Grafana dashboards must know what DB to read the data from. After loading the dashboards in Grafana, edit the name of $db variable. One change per dashboard.

Thank you. I did select the DB from dropdown when importing the dashboards so I believe we are good there.

For me the log file has not yet been created. which tells me that the collection did not run even after restarting telegraf.

cat /var/log/telegraf/telegraf.log cat: /var/log/telegraf/telegraf.log: No such file or directory

Collector not running is a separate issue. How did you install it? Are the permissions as required - all files owned by telegraf user. Delete the files if you manually ran the collector.

[protoss1232001]

Is there documentation on what the required permissions are? Sorry but I did not see that in readme file.

[protoss1232001]

Looks like a permissions issue.

Check this: https://www.since2k7.com/blog/2020/02/29/cisco-ucs-monitoring-using-grafana-influxdb-telegraf-utm-installation/

The steps are for UTM but applies to MTM also.

Thank you so much for that. I gave it a shot and got little further than before. Getting "Error in plugin" now. I'll go back and check again in some time if I missed any step.

this is the error from the log "ERROR - NXAPI error from 165.XX.XX.XXX:502:('bad_gateway',)" . Still looking but not sure what this means. Is it unable to reach the. switch and recieve response in timely manner?

As the error says, the switch is returning bad gateway. Try NXAPI sandbox before. If you want, drop an email to me and I can help to recover all these issues. My email is same as GitHub is at cisco.
