Datadog

Datadog

Datadog is a SaaS-based monitoring and analytics platform for IT infrastructure, operations and development teams. Datadog uses an open-source agent written in Python for gathering metrics and events. Its backend is built using a number of open and closed source technologies including D3, Apache, Cassandra, Kafka, PostgreSQL, etc.

Use the Datadog VNS3 plugin to gather performance data from all your application components, including major cloud providers and other VNS3 plugins including Varnish, Nginx, and Docker.

VNS3 versions 3.5 and newer have Docker-based container capabilities. Users can cut down on extra VMs running other network functions – including Datadog – in containers inside a VNS3 Controller. Now users can bundle things from load balancing, reverse proxy, and content cacheing inside a single VNS3 VM.

Use the Datadog VNS3 plugin to gather performance data from all your application components, including major cloud providers and other VNS3 plugins including Varnish, Nginx, and Docker.

For the Container plugin, use: ‘https://vns3-containers-read-all.s3.amazonaws.com/DataDog/DataDog_v1-0.tar.gz

In VNS3, use the following firewall rules:

#Port forward tcp44 to DataDog container for ssh
PREROUTING_CUST -i eth0 -p tcp --dport 44 -j DNAT --to [container_ip]:22

#SNAT for container network
MACRO_CUST -o eth0 -s [container_ip] -j MASQUERADE

#Accept incoming SNMP from DataDog container
INPUT_CUST -p udp -s [container_ip] --dport snmp -j ACCEPT
INPUT_CUST -p tcp --dport 8000 -s [container_ip] -j ACCEPT

#Allow returning SNMP traffic
OUTPUT_CUST -p udp -d [container_ip] --sport snmp -j ACCEPT
OUTPUT_CUST -p tcp --sport 8000 -d [container_ip] -j ACCEPT
