Demo about how to monitor Cisco ACI via REST-API with the TIG-Stack (Telegraf, InfluxDB, Grafana).

Visit GitHub CiscoACI_Grafana or my blog post over at NWMichl Blog for Telegraf configuration files and full documentation.

Shell scripts and may live in the /etc/telegraf directory and provide a wrapper around the API Call. Telegraf inputs.http doesn't support cookie handling, so I choose to break out to bash and use inputs.exec to parse the json response. Same for the cert / signature based authentication script, because nobody really wants to manual generate the signature and build the http header cookie by hand.

# Invoke: sh <APIC-FQDN or IP> <API-Operation> <username> <password>
# Example: sh /api/class/fabricHealthTotal.json telegraf telegraf

# Pipe bash arguments to variables

# Create random cookie filename to avoid race conditions by multiple, concurrent script executions

# APIC Login and store session cookie to /etc/telegraf
curl -s -k -d "<aaaUser name=$user pwd=$pass/>" -c /etc/telegraf/$cookiefilename -X POST https://$apic/api/mo/aaaLogin.xml > /dev/null

# APIC Query Operation using the session cookie
curl -s -k -X GET https://$apic$operation -b /etc/telegraf/$cookiefilename

# APIC Logout
curl -s -k -d "<aaaUser name=$user/>" -X POST https://$apic/api/mo/aaaLogout.json -b /etc/telegraf/$cookiefilename > /dev/null

# Remove session cookie
rm /etc/telegraf/$cookiefilename

Telegraf configuration

.conf files live in the /etc/telegraf/telegraf.d directory and query all metrics to populate the Grafana dashboard of this demo


The Dashboard is a first idea to visualize central Cisco ACI metrics and should help to get started developing own solutions.

Collector Configuration Details

Example Telegraf configuration file

  name_override = "ACI_APIC"
  commands = ["sh /etc/telegraf/ /api/class/infraWiNode.json telegraf telegraf"]
  timeout = "10s"
  data_format = "json"

  json_query = "imdata"
  tag_keys = ["infraWiNode_attributes_nodeName", "infraWiNode_attributes_addr"]
  json_string_fields = ["*health", "*apicMode", "*adminSt", "*operSt", "*failoverStatus"]
