prometheus node_exporter 监控项

截止2019-05-24 node_exporter监控项整理。

Collectors

每个操作系统对collector的支持各不相同。 下表列出了所有现有collector和支持的系统。通过--collector.<name>标志来启用collector。默认情况下启用的collector可以通过--no-collector.<name>标志来禁用。

默认情况下禁用

由于内核配置和安全设置，默认情况下，所有Linux系统上的perf收集器可能无法正常工作。 要允许访问，请设置以下sysctl参数：

sysctl -w kernel.perf_event_paranoid=X

2 仅允许用户空间度量（自Linux 4.6起默认）。

1 允许内核和用户度量（在Linux 4.6之前默认）。

0 允许访问特定CPU的数据，但不允许访问raw tracepoint samples。

-1 没有限制。

根据配置的值，将提供不同的度量标准，对于大多数情况，0将提供最完整的设置。 有关更多信息，请参阅man 2 perf_event_open。

Textfile Collector

textfile collector类似于Pushgateway因为它允许从批处理job导出统计信息。它还可用于导出静态指标，例如计算机具有的role。Pushgateway应该用于服务级别指标。textfile模式用于绑定计算机的度量标准。

要使用它，请在Node exporter上设置--collector.textfile.directory标志。collector将使用文本格式解析该目录中与glob *.prom匹配的所有文件。 注意：不支持时间戳。

以原子方式推送cron job的完成时间：

echo my_batch_job_completion_time $(date +%s) > /path/to/directory/my_batch_job.prom.$$
mv /path/to/directory/my_batch_job.prom.$$ /path/to/directory/my_batch_job.prom

使用标签静态设置计算机的roles：

echo 'role{role="application_server"} 1' > /path/to/directory/role.prom.$$
mv /path/to/directory/role.prom.$$ /path/to/directory/role.prom

Filtering enabled collectors

默认情况下，node_exporter将从启用的collector中公开所有指标。 这是收集指标以避免在比较不同系列的指标时出错的建议方法。

高级使用node_exporter可以传递一个可选的收集器列表来过滤指标。 collect[]参数可以多次使用。 在Prometheus配置中，您可以在scrape config

params:
  collect[]:
    - foo
    - bar

这对于让不同的Prometheus服务器从节点收集特定指标非常有用。

node_xfs_extent_allocation_extents_allocated_total	为文件系统分配的extent数 在电脑文件系统中，一个 Extent (在中国大陆某些文献中翻译为“区块”[1])，是指一段连续的存储空间。一般来说，一个文件的物理大小一定是一个 extent 容量的整数倍。当一个进程创建一个文件的时候，文件系统管理程序会将整个 extent 分配给这个文件。当再次向该文件写入数据时 (有可能是在其他写入操作之后)，数据会从上次写入的数据末尾处追加数据。这样可以减少甚至消除文件碎片。 参考：http://www.wikiwand.com/zh-sg/Extent_(%E6%AA%94%E6%A1%88%E7%B3%BB%E7%B5%B1)	# HELP node_xfs_extent_allocation_extents_allocated_total Number of extents allocated for a filesystem.
