Grafana 13.x + Graphite + Telegraf Linux Monitoring Lab Guide<\/h1>\n\n\n\n

Important validation from the real Graphite storage<\/h2>\n\n\n\n

The real collected metrics in this lab use this structure:<\/p>\n\n\n\n

telegraf.linux-demo.<measurement>.<field>\n<\/code><\/pre>\n\n\n\n
Therefore, use these queries:<\/p>\n\n\n\n
telegraf.linux-demo.cpu.usage_active\ntelegraf.linux-demo.cpu.usage_system\ntelegraf.linux-demo.mem.used_percent\ntelegraf.linux-demo.disk.used_percent\ntelegraf.linux-demo.net.bytes_recv\ntelegraf.linux-demo.system.load1\ntelegraf.linux-demo.processes.total\ntelegraf.linux-demo.processes.zombies\n<\/code><\/pre>\n\n\n\n
Do not use these older assumed tag-based paths in this lab:<\/p>\n\n\n\n
telegraf.linux-demo.cpu.cpu-total.usage_active\ntelegraf.linux-demo.disk.*.used_percent\ntelegraf.linux-demo.net.eth0.bytes_recv\ntelegraf.linux-demo.net.ens5.bytes_recv\n<\/code><\/pre>\n\n\n\n
Reason: the current Telegraf Graphite output template is storing metrics without CPU, disk mountpoint, and network interface tag nodes.<\/p>\n\n\n\n
\n\n\n\n
Step 1: Explore the Metrics Using Grafana Explore<\/h1>\n\n\n\n
Objective<\/h2>\n\n\n\n
Students will use Grafana Explore to discover and query Graphite metrics collected from Linux by Telegraf.<\/p>\n\n\n\n
1.1 Open Grafana Explore<\/h2>\n\n\n\n
Go to:<\/p>\n\n\n\n
Explore\n<\/code><\/pre>\n\n\n\n
Select the datasource:<\/p>\n\n\n\n
Graphite\n<\/code><\/pre>\n\n\n\n
Set time range:<\/p>\n\n\n\n
Last 15 minutes\n<\/code><\/pre>\n\n\n\n
Set refresh:<\/p>\n\n\n\n
10s\n<\/code><\/pre>\n\n\n\n
1.2 Validate the real metric paths before querying<\/h2>\n\n\n\n
On the Graphite server, run:<\/p>\n\n\n\n
docker exec -it graphite find \/opt\/graphite\/storage\/whisper\/telegraf -type f | sed 's#\/opt\/graphite\/storage\/whisper\/##; s#\/#.#g; s#.wsp$##' | sort\n<\/code><\/pre>\n\n\n\n
If output still shows .wsp<\/code>, remove .wsp<\/code> mentally when writing Grafana queries.<\/p>\n\n\n\n
Example file:<\/p>\n\n\n\n
telegraf.linux-demo.cpu.usage_active.wsp\n<\/code><\/pre>\n\n\n\n
Grafana query:<\/p>\n\n\n\n
