Troubleshoot cloud infrastructure monitoring

Updated: 2-21-2017

This section details potential performance, usage, and polling issues you may encounter with cloud infrastructure monitoring. If an issue occurs on the service side, review the Amazon Web Service (AWS) console for details and next steps. Some issues may require investigating your AWS account settings and minimums for requests and free request polling limits.

SAM and integrated VMAN  track cloud events in the Alerts & Events > Events manager and events resources on the Cloud Summary and Cloud Instance Details pages.

Issue: You are not authorized to perform this operation.

Troubleshooting: You will receive this error when you attempt Cloud Management actions such as stop, start, or terminate a cloud instance. Your AWS account may be read-only and require additional permissions. For details on AWS IAM user account permissions, see Learn more about Amazon EC2 credentials for cloud monitoring.

Issue: Data does not display in resources on Cloud Summary or Cloud Instance Details pages.

Troubleshooting: Check your AWS IAM account permissions. If you properly added your AWS account and cloud instances for monitoring, the AWS permissions may not be set correctly. For details on AWS IAM user account permissions, see Learn more about Amazon EC2 credentials for cloud monitoring.

Issue: Slowed performance when polling data.

Troubleshooting: Verify the amount of instances or nodes monitored and Orion agents deployed. Cloud Infrastructure Monitoring supports up to and recommends:

  • 10 AWS accounts
  • 1,000 instances to monitor
  • 1,000 volumes to monitor
  • 1,000 cloud instances managed as nodes
  • 1,000 deployed Orion agents on managed nodes

If you need to monitor beyond these amounts, SolarWinds recommends planning your monitoring for best performance and usage of your CloudWatch resources. The closer you meet or exceed supported Orion monitoring amounts may affect performance and poller load.

Issue: Error polling instance. Error polling volume.

This is a general error that displays if one or more polling issues occur to reduce the amount of events and alerts that display in the Orion Web Console. A description is included with the issue. This error displays for the specific instance or volume. The error generates if:

  • Error pulling one or more metrics for the instance

  • Access error when polling instance
  • Access error when polling volume

Troubleshooting: Review the following potential issues and resolutions:

  • For metric polling errors, check the log file.
  • AWS access issues: Check the AWS account access IDs and permissions in the AWS console and account information in the Orion Web Console.

Issue: Error polling instances for cloud account.

This is consolidated error that displays if one or more instances could not be polled or accessed. A list of all affected instances displays.

Troubleshooting: Check the AWS account access IDs and permissions in the AWS console and account information in the Orion Web Console.

Issue: Error polling volumes for cloud account.

This is consolidated error that displays if one or more attached volumes could not be polled or accessed. A list of all affected volumes displays.

Troubleshooting: Check the AWS account access IDs and permissions in the AWS console and account information in the Orion Web Console.

Issue: Error polling auto-scaling groups for cloud account.

This is consolidated error that displays if one or more auto-scaling groups could not be polled or accessed. A list of all affected auto-scaled groups displays.

Troubleshooting: Check the AWS account access IDs and permissions in the AWS console and account information in the Orion Web Console.

Issue: AWS throttling applied at the account, instance, or volume level. The instance displays as Unknown - AWS Throttling Error.

Troubleshooting: If AWS throttling occurs, verify any Orion alerts and review your AWS usage plans. The AWS API Gateway constantly checks the incoming requests against your AWS account limit. If your AWS polling requests exceed default or custom set thresholds, AWS throttling applies to your monitoring account, instances, and volumes blocking any requests beyond the limit.

The API accepts requests up to the acceptable requests per second: limits the steady-state request rates to 1000 requests per second (rps) and allows bursts of up to 2000 rps across all APIs, stages, and methods within an AWS account. AWS API Gateway responds to any requests beyond the limit with a 429 HTTP response for too many requests.

Issue: AWS CloudWatch polling limit threshold exceeded.

Troubleshooting: AWS CloudWatch provides a 1 million free polling request limit per month for all API metric polling. If the polling limit threshold is exceeded, verify any Orion alerts and review your AWS usage. SAM and integrated VMAN  displays your current CloudWatch polling usage through the account details per instance. To verify your monthly polling amount, edit the properties for your AWS account. Under the CloudWatch API polling section, review the calculated metric to determine usage for the month.

Be advised, Amazon Web Services does not halt polling or CloudWatch metrics. They charge an additional cost for the month based on the exceeded polls for the remaining time frame.

You can disable CloudWatch API polling in SAM and integrated VMAN at the account level. When disabled, only the instance status reports until polling CloudWatch is enabled.
