集成详情
VMware vSphere
此插件连接到 VMware vSphere 服务器以收集来自虚拟环境的各种指标,从而实现对虚拟资源的高效监控和管理。它与 vSphere API 接口,收集有关集群、主机、资源池、虚拟机、数据存储和 vSAN 实体的数据,并以适合分析和可视化的格式呈现。该插件对于管理基于 VMware 的基础设施的管理员尤其有价值,因为它有助于实时跟踪系统性能、资源使用情况和运营问题。通过聚合来自多个来源的数据,该插件使用户能够获得洞察力,从而有助于就资源分配、故障排除和确保最佳系统性能做出明智的决策。此外,对密钥存储集成的支持允许安全处理敏感凭据,从而在安全性和合规性评估方面推广最佳实践。
PostgreSQL
PostgreSQL 插件使用户能够将指标写入 PostgreSQL 数据库或兼容数据库,通过自动更新缺失的列,为模式管理提供强大的支持。该插件旨在促进与监控解决方案的集成,使用户能够高效地存储和管理时序数据。它为连接设置、并发和错误处理提供了可配置的选项,并支持高级功能,例如用于标签和字段的 JSONB 存储、外键标记、模板化模式修改以及通过 pguint 扩展支持无符号整数数据类型。

# Publishes metrics to a postgresql database
[[outputs.postgresql]]
## Specify connection address via the standard libpq connection string:
## host=... user=... password=... sslmode=... dbname=...
## Or a URL:
## postgres://[user[:password]]@localhost[/dbname]?sslmode=[disable|verify-ca|verify-full]
## See https://postgresql.ac.cn/docs/current/libpq-connect.html#LIBPQ-CONNSTRING
##
## All connection parameters are optional. Environment vars are also supported.
## e.g. PGPASSWORD, PGHOST, PGUSER, PGDATABASE
## All supported vars can be found here:
## https://postgresql.ac.cn/docs/current/libpq-envars.html
##
## Non-standard parameters:
## pool_max_conns (default: 1) - Maximum size of connection pool for parallel (per-batch per-table) inserts.
## pool_min_conns (default: 0) - Minimum size of connection pool.
## pool_max_conn_lifetime (default: 0s) - Maximum age of a connection before closing.
## pool_max_conn_idle_time (default: 0s) - Maximum idle time of a connection before closing.
## pool_health_check_period (default: 0s) - Duration between health checks on idle connections.
# connection = ""
## Postgres schema to use.
# schema = "public"
## Store tags as foreign keys in the metrics table. Default is false.
# tags_as_foreign_keys = false
## Suffix to append to table name (measurement name) for the foreign tag table.
# tag_table_suffix = "_tag"
## Deny inserting metrics if the foreign tag can't be inserted.
# foreign_tag_constraint = false
## Store all tags as a JSONB object in a single 'tags' column.
# tags_as_jsonb = false
## Store all fields as a JSONB object in a single 'fields' column.
# fields_as_jsonb = false
## Name of the timestamp column
## NOTE: Some tools (e.g. Grafana) require the default name so be careful!
# timestamp_column_name = "time"
## Type of the timestamp column
## Currently, "timestamp without time zone" and "timestamp with time zone"
## are supported
# timestamp_column_type = "timestamp without time zone"
## Templated statements to execute when creating a new table.
# create_templates = [
# '''CREATE TABLE {{ .table }} ({{ .columns }})''',
# ]
## Templated statements to execute when adding columns to a table.
## Set to an empty list to disable. Points containing tags for which there is no column will be skipped. Points
## containing fields for which there is no column will have the field omitted.
# add_column_templates = [
# '''ALTER TABLE {{ .table }} ADD COLUMN IF NOT EXISTS {{ .columns|join ", ADD COLUMN IF NOT EXISTS " }}''',
# ]
## Templated statements to execute when creating a new tag table.
# tag_table_create_templates = [
# '''CREATE TABLE {{ .table }} ({{ .columns }}, PRIMARY KEY (tag_id))''',

## Templated statements to execute when adding columns to a tag table.
## Set to an empty list to disable. Points containing tags for which there is no column will be skipped.
# tag_table_add_column_templates = [
# '''ALTER TABLE {{ .table }} ADD COLUMN IF NOT EXISTS {{ .columns|join ", ADD COLUMN IF NOT EXISTS " }}''',
# ]
## The postgres data type to use for storing unsigned 64-bit integer values (Postgres does not have a native
## unsigned 64-bit integer type).
## The value can be one of:
## numeric - Uses the PostgreSQL "numeric" data type.
## uint8 - Requires pguint extension (https://github.com/petere/pguint)
# uint64_type = "numeric"
## When using pool_max_conns>1, and a temporary error occurs, the query is retried with an incremental backoff. This
## controls the maximum backoff duration.
# retry_max_backoff = "15s"
## Approximate number of tag IDs to store in in-memory cache (when using tags_as_foreign_keys).
## This is an optimization to skip inserting known tag IDs.
## Each entry consumes approximately 34 bytes of memory.
# tag_cache_size = 100000
## Enable & set the log level for the Postgres driver.
# log_level = "warn" # trace, debug, info, warn, error, none
输入和输出集成示例
VMware vSphere
-
动态资源分配:使用此插件来监控虚拟机群的资源使用情况,并根据性能指标自动调整资源分配。这种情况可能涉及根据从 vSphere API 收集的 CPU 和内存使用率指标实时触发扩展操作,从而确保最佳性能和成本效益。
-
容量规划和预测:利用从 vSphere 收集的历史指标进行容量规划。分析 CPU、内存和存储使用率随时间变化的趋势,有助于管理员预测何时需要额外资源,避免中断并确保虚拟基础设施能够应对增长。
-
自动警报和事件响应:将此插件与警报工具集成,以根据收集的指标设置自动通知。例如,如果主机上的 CPU 使用率超过指定阈值,则可以触发警报并自动启动预定义的补救步骤,例如将虚拟机迁移到利用率较低的主机。
-
跨集群的性能基准测试:使用收集的指标来比较不同 vCenter 中集群的性能。此基准测试提供了关于哪种集群配置产生最佳资源效率的见解,并可以指导未来的基础设施增强。
PostgreSQL
-
使用复杂查询进行实时分析:利用 PostgreSQL 插件将来自各种来源的指标存储在 PostgreSQL 数据库中,从而可以使用复杂查询进行实时分析。这种设置可以帮助数据科学家和分析师发现模式和趋势,因为他们在利用 PostgreSQL 强大的查询优化功能的同时,跨多个表操作关系数据。具体来说,用户可以使用跨不同指标表的 JOIN 操作创建复杂的报告,从而揭示通常隐藏在嵌入式系统中的见解。
-
与 TimescaleDB 集成以进行时序数据处理:在 TimescaleDB 实例中使用 PostgreSQL 插件来高效处理和分析时序数据。通过实施超表,用户可以在时间维度上实现更高的性能和主题分区。这种集成允许用户对大量的时序数据运行分析查询,同时保留 PostgreSQL SQL 查询的全部功能,从而确保指标分析的可靠性和效率。
-
数据版本控制和历史分析:实施使用 PostgreSQL 插件的策略,以维护指标在不同时间段的不同版本。用户可以设置不可变的数据表结构,其中保留旧版本的表,从而可以轻松进行历史分析。这种方法不仅提供了对数据演变的洞察力,而且有助于遵守数据保留策略,确保数据集的历史完整性保持不变。
-
动态模式管理以适应不断变化的指标:使用插件的模板功能来创建动态变化的模式,以响应指标变化。此用例允许组织在指标演变时调整其数据结构,添加必要的字段并确保遵守数据完整性策略。通过利用模板化的 SQL 命令,用户无需手动干预即可扩展其数据库,从而促进敏捷数据管理实践。
