Study Notes
Zabbix Preprocessing and Prometheus Data Collection
- JSONPath is a functionality available for item value preprocessing in Zabbix, allowing the extraction and manipulation of data using logical expressions and operators.
- JSONPath examples demonstrate the usage of JSONPath expressions to select specific elements and values from JSON data, such as retrieving the price of a book or selecting elements from an array.
- Prometheus data collection involves using a Prometheus exporter to report metrics from third-party systems, and Zabbix can collect Prometheus data using HTTP item type and create dependent items with Prometheus pattern to retrieve specific metrics.
- The Prometheus format includes metadata lines like # HELP and # TYPE to identify metric names, types, and descriptions, and the Prometheus query language is used to extract data based on metric names, labels, and aggregation functions.
- Practical setup involves opening HTTP on a specific address to see Prometheus data, creating dependent items to retrieve CPU usage metrics, and setting up HTTP items to gather Prometheus data.
- Zabbix offers multiple preprocessing steps, including transformation to JSON from formats like CSV, XML, and Prometheus, which is useful for low level discovery (LLD) to automatically create items, triggers, and graphs based on JSON data.
- The CSV to JSON preprocessing step in Zabbix allows for the conversion of CSV format data into JSON format, with options to set custom delimiters, quotation symbols, and interpretation of the first line as column names.
