![]() The Logstash server running on EC2 polls information from devices running SNMP agents.The repo contains Logstash settings files, configuration files and an AWS CloudFormation template that automates the entire setup as explained later in the post.įigure 1 shows the solution architecture:įigure 1: Logstash server integration with SNMP enabled devices and Amazon CloudWatch metrics High-level steps In the GitHub repository, there are detailed deployment instructions for the example application. For more information, see the Importing MIBs in the Logstash documentation. These OIDs are ISO standard and do not require importing MIBs. These OIDs provide total input and output bytes for a given network interface and the system uptime since last reboot. In the example application, there are three object identifiers ( IfInOctets, IfOutOctets, and sysUpTimeInstance) configured to be polled every minute. You can expand this solution by using Logstash Snmptrap input plugin. I use AWS Secrets Manager and Logstash keystore for SNMP credential management. After Logstash processes the information, the output plugin forwards the metrics to CloudWatch using standard AWS APIs. These devices must be running SNMP daemons, listening on standard port 161 (Poll). The input plugin collects information (using SNMP polling) from the monitored devices. I use two Logstash plugins: SNMP (input plugin) and CloudWatch (output plugin). In this solution, Logstash acts as a relay server that sits between the managed devices that you want to monitor and Amazon CloudWatch. This solution does not cover SNMP traps or SNMP set commands. You can tailor the repository assets as appropriate for your needs. In this blog post, I provide a deployable demo and a walkthrough that you can use to set up an SNMP monitoring solution. You can establish a private virtual interface from your on-premises network directly to your VPC created in Amazon Virtual Private Cloud (Amazon VPC). You can use SNMP to monitor on-premises devices through AWS Direct Connect or AWS Site-to-Site VPN. Logstash is a free and open server-side data processing pipeline that ingests data from a multitude of sources, transforms it, and then sends it to your preferred analytics solution. ![]() Devices that typically support SNMP include routers, switches, firewalls, servers, and appliances. Simple Network Management Protocol (SNMP) is an internet standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior. Customers want a single pane of glass for their systems operations where they can visualize the health and performance of applications running in several AWS Regions and in their on-premises environment. ![]()
