Can't store data into influxdb #8

Open 4thdi opened 3 years ago

4thdi commented 3 years ago

The telegraf config: [[inputs.exec]] commands=["mtr -C -n 192.168.1.2"] timeout = "40s" data_format = "csv" csv_skip_rows = 1 csv_column_names=[ "", "", "status","dest","hop","ip","loss","snt","", "","avg","best","worst","stdev"] name_override = "mtr" csv_tag_columns = ["dest", "hop", "ip"]

[[outputs.influxdb]] urls = ["http://127.0.0.1:8086"] database = "my_telegraf3" timeout = "5s"

telegraf config file testing pass, but no mtr information display: telegraf --config /etc/telegraf/telegraf.conf --test

influxdb database creased normally, but no mtr measurement: Using database my_telegraf3

show measurements name: measurements name

cpu disk diskio kernel mem processes swap system

Please help to resovle this problem , what should I do? Many Thanks.

Hi, 4thdi.

The config looks good.

Is telegraf restarted after the config is updated? Does the log of telegraf tell anything related? And, what is the output of executing mtr -C -n 192.168.1.2 in a shell?

BTW, I would suggest adding an interval:

...
commands=["mtr -C -n 192.168.1.2"]
interval = "5m" # or 1m / 2m, whatever
timeout = "40s"
...

, even though it should be irrelevant to this problem.

Thanks for your answer, it seems not working. I have edited the config as you giving, and restart the telegraf, there is nothing in influxdb database.

Whether the problem is related to this configuration: "data_format"

[[inputs.exec]] 
data_format = "csv"

The command result "mtr -C -n example.org":

Whether the problem is related to this configuration: "data_format"

I think that is the problem. MTR.0.85 appears to indicate mtr v0.85 released in 2013, while the latest is v0.94 released in 2020. The output format turns out to change since then.

My output:

Try:

Their columns (csv_column_names) also differ somewhat. But I suppose it is fine because the several important fields are the same.

I don't have a mtr v0.85 to test. Please let me know if you find that still not working.

4thdi commented 3 years ago

Thanks a lot ! As you suggested, it's working now. Another question : How could I configure the panel options for GeoIP when I use it to monitor LAN network IP address? Source IP and destination IP address are LAN IP, it means I must manually define the GPS location.

Solution: Install MTR 0.94 manually(not by yum), then use it in inputs.exec

[[inputs.exec]]
  commands=["/tmp/mtr-0.94/mtr -C -n example.org"]
  interval = "60s"
  timeout = "120s"
  data_format = "csv"
  csv_skip_rows = 1
#  csv_delimiter = ";"
  csv_column_names=[ "", "", "status","dest","hop","ip","loss","snt","", "","avg","best","worst","stdev"]
  name_override = "mtr"
  csv_tag_columns = ["dest", "hop", "ip"]

Modify the output.influxdb timeout value:

[[outputs.influxdb]]
timeout = "120s"
Gowee commented 3 years ago

I am glad to hear that.

There is basically no support to allow specifying geolocation data manually for now. I am willing to learn about the actual scenario you are facing. Could you please elaborate on your network architecture?

For example, are all the hops (i.e. machines) with LAN IPs geographically dispersed over different places and connected via some tunnels (e.g. VPN)? Is there a known Internet IP address for each hop (even though only LAN IP is available in traceroute)?

BTW, it is not necessary to increase timeout of outputs.influxdb too much unless errors when flushing data are observed as it is irrelevant with exec. And a too-large timeout may prevent Telegraf from reporting db errors in time. Besides, in inputs.exec, I suppose timeout should be smaller than interval in general (not sure). Anyway, you do not have to change those until you see actual errors.

4thdi commented 3 years ago

Thanks for your prompt reply.

There are three sites in my network topology, they are in different city, the IP address are LAN. I need to monitor the network status between every two sites, the network exist VPN tunnel, and I can give the geographic coordinates of each city.

Now the require is:

  1. Mark the city of each site on the map;
  2. Show the network status through line status between each sites;

The MRT result as follows:

[root@ZABBAX-NET-TEST mtr-0.94]# /tmp/mtr-0.94/mtr -C -n 172.19.1.10

Hopefully this feature will be included in future releases, perhaps these requirements are out of the plug-in's design.

Gowee commented 3 years ago

Thanks for your feedback! The scenario sounds pretty reasonable. But there are some problems with the current implementation.

give the geographic coordinates of each city.

Mark the city of each site on the map;

Setting up a custom GeoIP API could be the most feasible way.

For example, on a serverless platform like Cloudflare Workers, a script can be as easy as: https://github.com/Gowee/traceroute-map-panel/blob/1d7b8d00d434f18fec1ea49526118cb35122a99a/ipip-cfworker.js. It gives full flexibility over geolocation data definition and takes no maintenance effort. If I have time, I would like to complement the example script later.

But due to the lack of source host IP in mtr output, the panel now resolves hostnames (host in data entry) to be the IP of an initial hop via a hardcoded DNS-over-HTTPS API. That is, it is not possible to control such hostname resolution for now. This problem would be easy to fix, though. It won't trouble if all of your hostnames are just IPs.

Show the network status through line status between each sites

Actually, line status does NOT indicate network status, at least for now. It is just a line connecting hops on a traceroute path, with fixed speed (assuming animation is turned on) and style. I was considering making line animations vary to reflect the network status (i.e. rtt and loss). But there is no concrete plan so far.

The hurdle is about both design (changing animation speed and dash length according to RTT and loss?) and implementation difficulty (say, it is somewhat infeasible to set different speeds for lines between every two hops while keeping animations smooth).

Hi.

I cannot reproduce the problem on a newly installed CentOS Linux release 8.4.2105. What is the version of telegraf and influxdb? Also, I am not sure what do you mean by "Always Fail". Is the telegraf failing to start? Or no data is written to influxdb?

Would you mind opening an issue where more information can be attached?

@Gowee This is my system environment for your reference
