Input and output integration overview
The Nginx plugin for Telegraf is designed to collect status metrics from Nginx web servers, providing real-time insights into server operation metrics.
The Stackdriver plugin allows users to send metrics directly to a specified project in Google Cloud Monitoring, facilitating robust monitoring capabilities across their cloud resources.
Integration details
Nginx
This plugin gathers status metrics from Nginx. It utilizes the ngx_http_stub_status_module to collect basic metrics related to the server’s performance. The plugin provides valuable insights into active connections, requests handled, and the current state of various metrics. This real-time data is essential for monitoring web server performance and ensuring optimal operations. The configuration allows users to specify the URL for the Nginx status endpoint, set timeouts, and configure TLS settings if necessary.
Google Cloud Monitoring
This plugin writes metrics to a project in Google Cloud Monitoring, which used to be known as Stackdriver. Authentication is a prerequisite and can be achieved via service accounts or user credentials. The plugin is designed to group metrics by a namespace
variable and metric key, facilitating organized data management. However, users are encouraged to use the official
naming format for enhanced query efficiency. The plugin supports additional configurations for managing metric representation and allows tags to be treated as resource labels. Notably, it imposes certain restrictions on the data it can accept, such as not allowing string values or points that are out of chronological order.
Configuration
Nginx
[[inputs.nginx]]
## An array of Nginx stub_status URI to gather stats.
urls = ["http://localhost/server_status"]
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
## HTTP response timeout (default: 5s)
response_timeout = "5s"
Google Cloud Monitoring
[[outputs.stackdriver]]
## GCP Project
project = "project-id"
## Quota Project
## Specifies the Google Cloud project that should be billed for metric ingestion.
## If omitted, the quota is charged to the service account’s default project.
## This is useful when sending metrics to multiple projects using a single service account.
## The caller must have the `serviceusage.services.use` permission on the specified project.
# quota_project = ""
## The namespace for the metric descriptor
## This is optional and users are encouraged to set the namespace as a
## resource label instead. If omitted it is not included in the metric name.
namespace = "telegraf"
## Metric Type Prefix
## The DNS name used with the metric type as a prefix.
# metric_type_prefix = "custom.googleapis.com"
## Metric Name Format
## Specifies the layout of the metric name, choose from:
## * path: 'metric_type_prefix_namespace_name_key'
## * official: 'metric_type_prefix/namespace_name_key/kind'
# metric_name_format = "path"
## Metric Data Type
## By default, telegraf will use whatever type the metric comes in as.
## However, for some use cases, forcing int64, may be preferred for values:
## * source: use whatever was passed in
## * double: preferred datatype to allow queries by PromQL.
# metric_data_type = "source"
## Tags as resource labels
## Tags defined in this option, when they exist, are added as a resource
## label and not included as a metric label. The values from tags override
## the values defined under the resource_labels config options.
# tags_as_resource_label = []
## Custom resource type
# resource_type = "generic_node"
## Override metric type by metric name
## Metric names matching the values here, globbing supported, will have the
## metric type set to the corresponding type.
# metric_counter = []
# metric_gauge = []
# metric_histogram = []
## NOTE: Due to the way TOML is parsed, tables must be at the END of the
## plugin definition, otherwise additional config options are read as part of
## the table
## Additional resource labels
# [outputs.stackdriver.resource_labels]
# node_id = "$HOSTNAME"
# namespace = "myapp"
# location = "eu-north0"
Input and output integration examples
Nginx
-
Web Performance Monitoring: Use the Nginx plugin to gather performance metrics from various Nginx servers across your infrastructure. By visualizing these metrics in real-time dashboards, teams can track performance trends, identify bottlenecks, and enhance the user experience on their web applications. Implementing such monitoring allows businesses to proactively address performance issues before they impact end-users.
-
Load Balancer Monitoring: Integrate this plugin with your load balancers to track the performance of backend Nginx servers. By collecting statistics like ‘active connections’ and ‘requests handled’, your operations team can ensure that traffic is flowing optimally and that no single server is overwhelmed. This proactive approach to load balancing prevents service downtime and enhances user experience.
-
Automated Alerting Systems: Combine the Nginx plugin with alerting services to automatically notify your team when a server’s metrics exceed predefined thresholds. For instance, if the number of active connections is too high, the system can trigger alerts so that corrective actions can be taken immediately, thus maintaining service quality and reliability.
-
Historical Data Analysis: Store the metrics collected by the Nginx plugin in a time-series database to analyze historical performance trends. This analysis can uncover periods of high traffic or poor performance, allowing for data-driven decisions about infrastructure scaling and optimization. By understanding past trends, organizations can better prepare for future demands.
Google Cloud Monitoring
-
Multi-Project Metric Aggregation: Use this plugin to send aggregated metrics from various applications across different projects into a single Google Cloud Monitoring project. This use case helps centralize metrics for teams managing multiple applications, providing a unified view for performance monitoring and enhancing decision-making. By configuring different quota projects for billing, organizations can ensure proper cost management while benefiting from a consolidated monitoring strategy.
-
Anomaly Detection Setup: Integrate the plugin with a machine learning-based analytics tool that identifies anomalies in the collected metrics. Using the historical data provided by the plugin, the tool can learn normal baseline behavior and promptly alert the operations team when unusual patterns arise, enabling proactive troubleshooting and minimizing service disruptions.
-
Dynamic Resource Labeling: Implement dynamic tagging by utilizing the tags_as_resource_label option to adaptively attach resource labels based on runtime conditions. This setup allows metrics to provide context-sensitive information, such as varying environmental parameters or operational states, enhancing the granularity of monitoring and reporting without changing the fundamental metric structure.
-
Custom Metric Visualization Dashboards: Leverage the data collected by the Google Cloud Monitoring output plugin to feed a custom metrics visualization dashboard using a third-party framework. By visualizing metrics in real-time, teams can achieve better situational awareness, notably by correlating different metrics, improving operational decision-making, and streamlining performance management workflows.
