      For example, --remote-read-headers='My-Auth:foobar' would send 'My-Auth: foobar' HTTP header with every request to the corresponding remote source storage. 
      Multiple headers must be delimited by '^^': --remote-read-headers='header1:value1^^header2:value2'

   --vm-addr value                     VictoriaMetrics address to perform import requests. 
      Should be the same as --httpListenAddr value for single-node version or vminsert component. 
      When importing into the clustered version do not forget to set additionally --vm-account-id flag. 
      Please note, that vmctl performs initial readiness check for the given address by checking /health endpoint. (default: "http://localhost:8428")

   --vm-password value    VictoriaMetrics password for basic auth [$VM_PASSWORD]
   --vm-account-id value  AccountID is an arbitrary 32-bit integer identifying namespace for data ingestion (aka tenant). 
      AccountID is required when importing into the clustered version of VictoriaMetrics. 
      It is possible to set it as accountID:projectID, where projectID is also arbitrary 32-bit integer. 
      If projectID isn't set, then it equals to 0

Zero value saves all the significant figures. This option may be used for increasing on-disk compression level for the stored metrics. See also --vm-round-digits option (default: 0)
   --vm-round-digits value                            Round metric values to the given number of decimal digits after the point. This option may be used for increasing on-disk compression level for the stored metrics (default: 100)

   --vm-backoff-factor value        Factor to multiply the base duration after each failed import retry. Must be greater than 1.0 (default: 1.8)
