My plugins for Telegraf.

cloudinsights-snmp-switch.conf

With this plugin you can monitor a switch with Cloud Insights via SNMP. This has been tested with a Cisco Nexus 9372. You need to tweak it for your switch model.

  1. Put the file cloudinsights-snmp-switch.conf into /etc/telegraf/telegraf.d

  2. Change

    • agents = ["<switch_ip_address>"]
    • url = "https://<your_tenant>.c01.cloudinsights.netapp.com/rest/v1/lake/ingest/influxdb"
    • X-CloudInsights-ApiKey = "<your_netapp_cloud_insights_apikey>"

Requirements - cloudinsights-snmp-switch.conf

net-snmp

Install snmp e.g. apt-get install snmp

MIBs

You can put the required MIBs into /etc/telegraf/.snmp/mibs

For this example I used

  • CISCO-ENTITY-FRU-CONTROL.MIB
  • CISCO-IF-EXTENSION-MIB
  • CISCO-SMI.MIB
  • IF-MIB
  • RFC1213-MIB
  • SNMPv2-SMI

Troubleshooting

Use snmpwalk to check if it is possible to get metrics from the switch

snmpwalk -v2c -m +ALL -c public <switch_ip_address>

Check logfiles

  • /var/log/telegraf/telegraf.log
  • /var/log/telegraf/telegraf-snmp-switch.json

cloudinsights-sqlserver.conf

With this plugin you can monitor a MS SQL Server with Cloud Insights.

Be aware of the counter_types when configurihttps://troubleshootingsql.com/2011/03/03/what-does-cntr_type-mean/ng dashboards/widgets! A good explanation can be found here

  1. Put the file cloudinsights-sqlserver.conf into C:\Program Files\telegraf\telegraf.d

  2. Change

    • url = "https://<your_tenant>.c01.cloudinsights.netapp.com/rest/v1/lake/ingest/influxdb"

    • X-CloudInsights-ApiKey = "<your_netapp_cloud_insights_apikey>"

    • <SQL_Server_IP>

    • <SQL_Server_User>

    • <SQL_Server_User_Password>

      servers = [
  "Server=<SQL_Server_IP>;Port=1433;User Id=<SQL_Server_User>;Password=<SQL_Server_User_Password>;app name=telegraf;log=1;",
]

Requirements - cloudinsights-sqlserver.conf

  • Install the Windows Data Collector with Cloud Insights
  • I recommend the following setting for the cloudinsights-default.conf
    • interval = "60s"
    • metric_batch_size = 5000
    • and for troubleshooting debug = true

General Troubleshooting

/usr/bin/telegraf --config /etc/telegraf/telegraf.conf --config-directory /etc/telegraf/telegraf.d --test
