External Thunder Observability Agent (TOA)
The external Thunder Observability Agent (TOA) is a lightweight autonomous data processing engine that can be externally installed and configured for any Thunder device.
The TOA offers the following capabilities for Thunder® Application Delivery Controller (ADC):
- Collects, processes, and publishes 14 Thunder metrics. The default data collection frequency is 1 minute. Thunder metrics can be sent to the platform where Thunder is deployed, which includes AWS, Azure, and VMware or can be sent to shared platforms like Elasticsearch (Kibana), Prometheus (Grafana), Splunk, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI). Metrics can be sent to any one platform at a time. For more information on Thunder metrics, see Supported Thunder Metrics.
- Collects, processes, and publishes Thunder Syslogs. The default data collection frequency is 1 minute. The logs can be published on various platforms like AWS, Azure, VMware, Kibana (Elasticsearch), Grafana (Prometheus and Pushgateway), Splunk, GCP, and OCI. Logs can be sent to any one platform at a time. For more information on Thunder logs, see Supported Thunder Logs.
- Manages the data collection, processing, aggregation, and publishing internally.
- Provides multitasking capabilities to collect and process data from multiple Thunder instances and their partitions simultaneously. By default, it collects data from a shared partition.
- TOA supports Shared and L3V partitions. The maximum number of partitions supported per Thunder is 20.
- Installs on any orchestration platform such as public cloud compute instances, private cloud physical or virtual machines, hypervisor VMs, and on-premise physical hardware and is self-driven.
- Installs on Linux, CentOS, and Ubuntu platforms as a Python Plugin installation package and Docker containerization.
- Supports single or multiple Thunder instances.
- Supports Thunder instances running under AWS Auto Scaling Group or Azure Virtual Machine Scale Set (VMSS).
- Collects data from any type of Thunder device installed on public cloud compute instances, private cloud physical or virtual machines, hypervisor VMs, and on-premise physical hardware installation.
- Publishes data to Azure Cloud, AWS Cloud, VMware ESXi, Kibana (Elasticsearch), Grafana (Prometheus and Pushgateway), Splunk,GCP, and OCI.
