 Description   

Steps to reproduce:

  1. Download template AWS EC2 by HTTP
  2. Create API Key/secret in AWS, setup permissions
  3. Configure host in Zabbix (required macros)

Result:
Result converted to text: {"error":"TypeError: cannot read property 'item' of null."}
**

Expected:
Returned list of EBS volumes

Solution:
{}Remove this line from JavaScript:
{{}}

payload['MaxResults'] = 100,

By tests: AWS API is getting first 100 volumes, after this is applying filter on this result

Part of Javascript before:

payload['Action'] = 'DescribeVolumes',
payload['Version'] = '2016-11-15',
payload['Filter.1.Name'] = 'attachment.instance-id',
payload['Filter.1.Value'] = AwsEbs.params.instance_id;

Part of Javascript after modification:

payload['Action'] = 'DescribeVolumes',
payload['MaxResults'] = 100,
payload['Version'] = '2016-11-15',
payload['Filter.1.Name'] = 'attachment.instance-id',
payload['Filter.1.Value'] = AwsEbs.params.instance_id;

Item: aws.ec2.get_volumes

Similar problem is in item: aws.ec2.get_alarms

Hello, jirimikes!
What is the largest number of vol on one EC2?

I was unable to reproduce the issue in 6.0.19. 

1. Create AWS EC2 with 9 vol. 

2. Reduced the number to 5 in JS 

payload['MaxResults'] = 5

Can you show the logs and the test result in the web interface

add this string in JS to see raw data

Zabbix.log(3, '[ AWS EBS ] VOL: ' + JSON.stringify(volumes))

example logs

Please note that I spend allot of time with Amazon on this and found out that there documentation (DescribeVolumes - Amazon Elastic Compute Cloud) states the following:

nextToken

The token to include in another request to get the next page of items. This value is null when there are no more items to return.

 

This basically means that you need to loop until the nextToken is null. I have made an update to the code to accommodate this with the MaxResults still set to 100 and it returns the results correctly now. Please note that this is the way every AWS API works. I also fixed the fact that nextToken was spelled as NextToken in this loopkup:

volumes.DescribeVolumesResponse.nextToken
