Output filter, Elasticsearch & cloud instance

Mark_Rodman · July 22, 2022, 9:37am

Hi,
Hope you are all well.

I've been building a new Logstash pipeline and testing against a local instance of Elasticsearch on my network which is running fine without any security. The process has been pretty straightforward.

I'm now trying to shift the output from the local ES instance to our production cloud ES service, but I'm struggling, any advice would be appreciated.

My successful local deployment config output filter is as follows;

elasticsearch {
                hosts => [ "10.81.1.248:9200" ]
                index => "proxylogs-%{+YYYY.MM.dd}"
                action => "index"
                manage_template => true
                template => "/usr/share/logstash/template/proxylogs-template.json"
                template_name => "proxylogs"
                template_overwrite => true
            }

I've tried various configuration possibilities, such as;

            elasticsearch {
            
                hosts => "https://xxxxxxxxxxxxxx.gcp.elastic-cloud.com:9243"
                ssl => true
                ssl_certificate_verification => false
                user => "xxxxxx"
                password => "xxxxxxx"
                index => "dnslogs-%{+YYYY.MM.dd}"
                action => "index"
                manage_template => true
                template => "/usr/share/logstash/template/dnslogs-template.json"
                template_name => "dnslogs"
                template_overwrite => true
            }

The user and password are correct and should have the appropriate permissions.

I'm getting the following error;

[2022-07-22T10:12:54,763][WARN ][logstash.outputs.elasticsearch][main] Attempted to resurrect connection to dead ES instance, but got an error {:url=>"https://user:xxxxxx@xxxxxx.gcp.elastic-cloud.com:9243/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError, :message=>"Got response code '401' contacting Elasticsearch at URL 'https://xxxxxxxxxx.gcp.elastic-cloud.com:9243/'"}

I'm using logstash v7.17 and ES cloud v7.16.1

Thanks for the help

Hi @Mark_Rodman

A couple things where exactly did you get the endpoint from? You should get it from the elastic cloud console.

2nd there should be a .es or .kb component of the url..

https://xxxxxxxxx.es.us-west1.gcp.cloud.es.io

3rd you don't need the :9243 anymore

Finally you should be able to curl the ES endpoint from the logstash machine

curl -u "username:password" https://xxxxxxxxx.es.us-west1.gcp.cloud.es.io

{
  "name" : "instance-0000000095",
  "cluster_name" : "asdfasdfasdfasdf",
  "cluster_uuid" : "safdasdfsadfasdf",
  "version" : {
    "number" : "8.2.3",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "9905bfb62a3f0b044948376b4f607f70a8a151b4",
    "build_date" : "2022-06-08T22:21:36.455508792Z",
    "build_snapshot" : false,
    "lucene_version" : "9.1.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

You can also use

output {
  elasticsearch { 
    cloud_id => "<cloud id>"
    cloud_auth => "<cloud auth>" 
  } 
}

Mark_Rodman · July 22, 2022, 7:22pm

thanks,
Can you confirm if the host variable xxxxxxx values should be the id of human readable name?
Cheers

stephenb · July 22, 2022, 7:45pm

I don't know what that means... my screen shot showed you exactly where to get it from.
If you mean the custom alias endpoint .. .then yes

Mark_Rodman · July 22, 2022, 7:47pm

Apologies, you are correct,
I've successfully used curl, now to try the logstash output.

{
  "name" : "instance-0000000012",
  "cluster_name" : "xxxxxxx",
  "cluster_uuid" : "2xxxxx",
  "version" : {
    "number" : "7.16.1",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "xxxxxx",
    "build_date" : "2021-12-11T00:29:38.865893768Z",
    "build_snapshot" : false,
    "lucene_version" : "8.10.1",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

Mark_Rodman · July 22, 2022, 7:56pm

Unfortunately the config still errors as follows;

[2022-07-22T20:51:24,715][WARN ][logstash.outputs.elasticsearch][main] Attempted to resurrect connection to dead ES instance, but got an error {:url=>"https://logstash:xxxxxx@XXXXXXXX.es.europe-west2.gcp.elastic-cloud.com:9200/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :message=>"Elasticsearch Unreachable: [https://XXXXXX.es.europe-west2.gcp.elastic-cloud.com:9200/][Manticore::ConnectTimeout] Connect to XXXXXXXX.es.europe-west2.gcp.elastic-cloud.com:9200 [XXXXXX.es.europe-west2.gcp.elastic-cloud.com/34.89.12.12] failed: connect timed out"}

I'm using

elasticsearch {
                hosts => [ "https://XXXXX.es.europe-west2.gcp.elastic-cloud.com" ]
                user => "logstash"
                password => "***"
                index => "dnslogs-%{+YYYY.MM.dd}"
                action => "index"
                manage_template => true
                template => "/usr/share/logstash/template/dnslogs-template.json"
                template_name => "dnslogs"
                template_overwrite => true
            }

I notice the port has gone back to 9200, is that correct for the cloud? Surely it should be 9243?

Thanks

Mark_Rodman · July 22, 2022, 8:12pm

I added :9243 to the address in the hosts array, it didn't help, came back with a 401.

I then added :9243 and then :443 to the address used when testing with curl. Both worked with curl, but yet, bot refuse within logstash, producing;

[2022-07-22T21:06:37,292][WARN ][logstash.outputs.elasticsearch][main] Attempted to resurrect connection to dead ES instance, but got an error {:url=>"https://logstash:xxxxxx@xxxxxxxx.es.europe-west2.gcp.elastic-cloud.com:9243/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError, :message=>"Got response code '401' contacting Elasticsearch at URL 'https://xxxxxxxxxx.es.europe-west2.gcp.elastic-cloud.com:9243/'"}

@stephenb any ideas ???? I'm totally stuck.

stephenb · July 22, 2022, 8:33pm

And you tried the curl from the same server that logsstash is running on? not some other server?

The service runs on 9243 and 443 not 9200 so that will never work

Did you try just with no port and no /

https://logstash:xxxxxx@xxxxxxxx.es.europe-west2.gcp.elastic-cloud.com

Also how are you starting logstash from command line or systemctl?

Mark_Rodman · July 22, 2022, 8:37pm

logstash is running on a linux box on my home net, connecting to the cloud.
I ran,

root@mark-linux:/etc/logstash/conf.d# curl -u "logstash:mypassword" https://xxxxxxx.es.europe-west2.gcp.elastic-cloud.com
{
  "name" : "instance-0000000001",
  "cluster_name" : "xxxxxxxx",
  "cluster_uuid" : "xxxxxxxxxxx",
  "version" : {
    "number" : "7.16.1",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "xxxxxxxxxxxx",
    "build_date" : "2021-12-11T00:29:38.865893768Z",
    "build_snapshot" : false,
    "lucene_version" : "8.10.1",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

I'm start Logstash with;
service logstash start

I used the same method when testing against my local ES instance.

stephenb · July 22, 2022, 8:40pm

Logstash as a service runs under a different account logstash user I believe... perhaps you have a FW rule in place that does not let the logstash user make exeternal connections...

Try starting logstash from the command line with the same user as you curl

There is nothing special about connecting to cloud except it is remote...

Ohh shoot try putting the :443 in ... yes logstash will default to try port 9200 when you leave the port off you can see that in the message above perhaps you have a FW blocking :9243

Mark_Rodman · July 22, 2022, 8:47pm

@stephenb I got the same response.
I ran as follows, which logged to the console the correct config loading, but ultimately produced the same 401 error.

/usr/share/logstash/bin/logstash --path.settings /etc/logstash/

To be honest there isn't any egress control on the network, it's my home working environment.

The cloud environment has SSO enabled, could that be a factor?

stephenb · July 22, 2022, 8:53pm

Perhaps But you successfully curl ed so no I would not think so.

401 error is bad Auth and when I can not see the actual configuration (except password) and the actual output hard for me to help.. it is something simple.

Can you show the elastic output section and the actual logs from the above command .. otherwise I am just guessing.... to help debug it is good to see that for every iteration..

Do you have a typo in the password?

Mark_Rodman · July 22, 2022, 8:53pm

also nmap'd it

root@mark-linux:/etc/logstash# nmap xxxxxxxx.es.europe-west2.gcp.elastic-cloud.com -p9243

it's not connectivity.....

Thanks.. OK here is what I got...

401 Is Bad Auth (as I am sure you know)... not connectivity (as you demonstrated), something wrong with your username / password / role combination. Its is connecting and Auth is denied.

SSO ... hmm... That should not get in the way since you can curl but I am not positive... but I do not think it is that. I assume your logstash creds are "native" realm I assume so they cascade to the native realm, that is how the curl is working.

I think I have an idea... your logstash user may not have the correct roles / privileges for logstash to authenticate and properly connect but it does have enough privileges to do the simple curl command.

Per the docs here These are the roles that logstash user will need.

POST _security/role/logstash_writer
{
  "cluster": ["manage_index_templates", "monitor", "manage_ilm"], 
  "indices": [
    {
      "names": [ "logstash-*" ], <--- Add your other indices here 
      "privileges": ["write","create","create_index","manage","manage_ilm"]  
    }
  ]
}

Do you have another user to try and / or you will need to check the roles / privileges on that logstash user.

I suspect you are using the elastic superuser on your local host so that is why they work.

I would take look at the roles / permissions for that logstash user.

Mark_Rodman · July 22, 2022, 9:39pm

Thanks.
I did go a bit crazy adding every permission under the sun trying to fix, but I've reduce the perms to match your recommendation;
Output as followsi

GET _security/role/logstash_writer
{
  "logstash_writer" : {
    "cluster" : [
      "manage_index_templates",
      "manage_ingest_pipelines",
      "manage_ilm",
      "monitor"
    ],
    "indices" : [
      {
        "names" : [
          "*",
          "logs-*",
          "dnslogs-*",
          "proxylogs-*",
          "iplogs-*",
          "logstash-*"
        ],
        "privileges" : [
          "create_doc",
          "create_index",
          "create",
          "index",
          "write",
          "delete",
          "manage",
          "manage_ilm"
        ],
        "field_security" : {
          "grant" : [
            "*"
          ],
          "except" : [ ]
        },
        "allow_restricted_indices" : false
      }
    ],
    "applications" : [
      {
        "application" : "kibana-.kibana",
        "privileges" : [
          "all"
        ],
        "resources" : [
          "*"
        ]
      }
    ],
    "run_as" : [ ],
    "metadata" : { },
    "transient_metadata" : {
      "enabled" : true
    }
  }
}

So I should be good....

stephenb · July 22, 2022, 9:44pm

Does it Work?

You can always do a test with the elastic user first then work on your writer role

Mark_Rodman · July 22, 2022, 9:46pm

Sadly not, still the same,
I don't have the Elastic account password either.
