AWS output/aggregator with unexpected missing indicators

Hello,

I have a dev and prod instance of MM. Noticed both dev and prod behaving the same way, where many indicators were not showing up in output feed for AWS miners. Config on both is the following:

nodes:
  aws_route53_miner:
    inputs: []
    output: true
    prototype: aws.ROUTE53
  aws_ipv4_output:
    inputs:
      - aws_ipv4_aggregator
    output: false
    prototype: stdlib.feedHCWithValue
  aws_s3_miner:
    inputs: []
    output: true
    prototype: minemeldlocal.aws_S3
  aws_ec2_miner:
    inputs: []
    output: true
    prototype: aws.EC2
  aws_amazon_miner:
    inputs: []
    output: true
    prototype: aws.AMAZON
  aws_ipv4_aggregator:
    inputs:
      - aws_cloudfront_miner
      - aws_ec2_miner
      - aws_route53_miner
      - aws_route53_healthchecks_miner
      - aws_amazon_miner
      - aws_s3_miner
    output: true
    prototype: stdlib.aggregatorIPv4Generic
  aws_cloudfront_miner:
    inputs: []
    output: true
    prototype: aws.CLOUDFRONT
  aws_route53_healthchecks_miner:
    inputs: []
    output: true
    prototype: aws.ROUTE53_HEALTHCHECKS

Dev/Prod both showed the same # of indicators on Nodes tab:

aws_amazon_miner 511

aws_cloudfront_miner 35

aws_ec2_miner 222

aws_route53_healthchecks_miner 16

aws_route53_miner 2

aws_s3_miner 62

aws_ipv4_aggregator 323

aws_ipv4_output 346

I made a change in dev to take the aws_amazon_miner with 511 indicators straight to an output.

nodes:
  aws_test_full_output:
    inputs:
      - aws_amazon_miner
    output: false
    prototype: stdlib.feedHCWithValue

The result is that the issue is not seen on this output, but the original aggregator and output nodes also had the issue go away for the time being:

aws_ipv4_aggregator 848

aws_ipv4_output 577

aws_test_full_output 511

Was planning to go production with this AWS output next week. Need to vet out this issue asap.

Attaching engine logs from both instances as well as copys of output feeds in multiple versions.

prod 0.9.36

dev 0.9.38

Hi @andrew.stanton,

thanks, this is a bug and will be fixed in the next release. Details here: https://github.com/PaloAltoNetworks/minemeld-core/issues/213

A workaround is forcing a flush and an update on the existing miner you just added to the aggregator:

$ /opt/minemeld/engine/current/bin/mm-console signal flush aws_amazon_miner
$ /opt/minemeld/engine/current/bin/mm-console hup aws_amazon_miner
