The basic installation of Grafana InfluxDB and Telegraf is described in my other post here-
Install Grafna, InfluxDB, Telegraf for Jitsi Video Meet Monitoring on Debian 10
All is needed is to create a telegraf configuration file:
nano /etc/telegraf.d/dashboard.conf
# Global tags can be specified here in key="value" format. [global_tags] # dc = "us-east-1" # will tag all metrics with dc=us-east-1 # rack = "1a" ## Environment variables can be used as tags, and throughout the config file # user = "$USER" # Configuration for telegraf agent [agent] interval = "10s" round_interval = true metric_batch_size = 1000 metric_buffer_limit = 10000 collection_jitter = "0s" flush_interval = "10s" flush_jitter = "0s" precision = "" debug = false quiet = false hostname = "" omit_hostname = false ### OUTPUT # Configuration for influxdb server to send metrics to [[outputs.influxdb]] urls = ["http://your_host:8086"] database = "telegraf_metrics" ## Retention policy to write to. Empty string writes to the default rp. retention_policy = "" ## Write consistency (clusters only), can be: "any", "one", "quorum", "all" write_consistency = "any" ## Write timeout (for the InfluxDB client), formatted as a string. ## If not provided, will default to 5s. 0s means no timeout (not recommended). timeout = "5s" # username = "telegraf" # password = "2bmpiIeSWd63a7ew" ## Set the user agent for HTTP POSTs (can be useful for log differentiation) # user_agent = "telegraf" ## Set UDP payload size, defaults to InfluxDB UDP Client default (512 bytes) # udp_payload = 512 # Read metrics about cpu usage [[inputs.cpu]] ## Whether to report per-cpu stats or not percpu = true ## Whether to report total system cpu stats or not totalcpu = true ## Comment this line if you want the raw CPU time metrics fielddrop = ["time_*"] # Read metrics about disk usage by mount point [[inputs.disk]] ## By default, telegraf gather stats for all mountpoints. ## Setting mountpoints will restrict the stats to the specified mountpoints. # mount_points = ["/"] ## Ignore some mountpoints by filesystem type. For example (dev)tmpfs (usually ## present on /run, /var/run, /dev/shm or /dev). ignore_fs = ["tmpfs", "devtmpfs"] # Read metrics about disk IO by device [[inputs.diskio]] ## By default, telegraf will gather stats for all devices including ## disk partitions. ## Setting devices will restrict the stats to the specified devices. # devices = ["sda", "sdb"] ## Uncomment the following line if you need disk serial numbers. # skip_serial_number = false # Get kernel statistics from /proc/stat [[inputs.kernel]] # no configuration # Read metrics about memory usage [[inputs.mem]] # no configuration # Get the number of processes and group them by status [[inputs.processes]] # no configuration # Read metrics about swap memory usage [[inputs.swap]] # no configuration # Read metrics about system load & uptime [[inputs.system]] # no configuration # Read metrics about network interface usage [[inputs.net]] # collect data only about specific interfaces # interfaces = ["eth0"] [[inputs.netstat]] # no configuration [[inputs.interrupts]] # no configuration [[inputs.linux_sysctl_fs]] # no configuration
Update the necessary paramaters accordign to your installations.
