Linux Monitoring using Grafana InfluxDB and Telegraf on Debian 10

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.
