Proxmox 7 and InfluxDB 2

Telegraf
1

Hi to all,

I’m new to InfluxDB and I’m not able to monitor Proxmox 7. I have installed Telegraf on Proxmox with the following conf:

# Configuration for telegraf agent
[agent]
  ## Default data collection interval for all inputs
  interval = "10s"
  ## Rounds collection interval to 'interval'
  ## ie, if interval="10s" then always collect on :00, :10, :20, etc.
  round_interval = true

  ## Telegraf will send metrics to outputs in batches of at most
  ## metric_batch_size metrics.
  ## This controls the size of writes that Telegraf sends to output plugins.
  metric_batch_size = 1000

  ## For failed writes, telegraf will cache metric_buffer_limit metrics for each
  ## output, and will flush this buffer on a successful write. Oldest metrics
  ## are dropped first when this buffer fills.
  ## This buffer only fills when writes fail to output plugin(s).
  metric_buffer_limit = 10000

  ## Collection jitter is used to jitter the collection by a random amount.
  ## Each plugin will sleep for a random time within jitter before collecting.
  ## This can be used to avoid many plugins querying things like sysfs at the
  ## same time, which can have a measurable effect on the system.
  collection_jitter = "0s"

  ## Default flushing interval for all outputs. Maximum flush_interval will be
  ## flush_interval + flush_jitter
  flush_interval = "10s"
  ## Jitter the flush interval by a random amount. This is primarily to avoid
  ## large write spikes for users running a large number of telegraf instances.
  ## ie, a jitter of 5s and interval 10s means flushes will happen every 10-15s
  flush_jitter = "0s"

  ## By default or when set to "0s", precision will be set to the same
  ## timestamp order as the collection interval, with the maximum being 1s.
  ##   ie, when interval = "10s", precision will be "1s"
  ##       when interval = "250ms", precision will be "1ms"
  ## Precision will NOT be used for service inputs. It is up to each individual
  ## service input to set the timestamp at the appropriate precision.
  ## Valid time units are "ns", "us" (or "µs"), "ms", "s".
  precision = ""

  ## Logging configuration:
  ## Run telegraf with debug log messages.
  debug = false
  ## Run telegraf in quiet mode (error log messages only).
  quiet = false
  ## Specify the log file name. The empty string means to log to stderr.
  logfile = ""

  ## Override default hostname, if empty use os.Hostname()
  hostname = ""
  ## If set to true, do no set the "host" tag in the telegraf agent.
  omit_hostname = false
[[outputs.influxdb_v2]]	
  ## The URLs of the InfluxDB cluster nodes.
  ##
  ## Multiple URLs can be specified for a single cluster, only ONE of the
  ## urls will be written to each interval.
  ## urls exp: http://127.0.0.1:8086
  urls = ["https://my_influxdb_url:8086"]

  ## Token for authentication.
  token = "$INFLUX_TOKEN"

  ## Organization is the name of the organization you wish to write to; must exist.
  organization = "Proxmox Servers"

  ## Destination bucket to write into.
  bucket = "Proxmox Infra"
  insecure_skip_verify = true
[[inputs.proxmox]]
  ## API connection configuration. The API token was introduced in Proxmox v6.2. Required permissions for user and token: PVEAuditor role on /.
  base_url = "https://prox-monitor1.proximacomputing.it:8006/api2/json"
  # api_token = "USER@REALM!TOKENID=UUID"
  api_token = "Monitor@pam!monitor=aa4gcfc7-810y-4dc3-af91-133fe6b60423"
  ## Node name, defaults to OS hostname
  # node_name = ""

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  #insecure_skip_verify = false
  insecure_skip_verify = true
  # HTTP response timeout (default: 5s)
  response_timeout = "5s"

In InfluxDB I have configured an Organization “Proxmox Servers” and a Bucket “Proxmox Infra”. I have also, in Proxmox 7.0.11 Server, correctly export the INFLUX_TOKEN.

Now in Proxmox Server syslog I have the following error:

E! [inputs.proxmox] Error getting VM stats: %vjson: cannot unmarshal number into Go struct field VMStat.data.vmid of type string

And nothing is sent to InfluxDB server.

In Proxmox I have created a user “Monitor” and an API token with:

  • Permission “PVEAuditor”
  • Path: /

Could you help me, please?

Thank you
