cannot process json request

[lbardelli]

Hi Ike,

I try ZWAS on Zabbix 3.0, and he can discovery my hosts, but without any information...

On zabbix_server.log, I have this error:

2205:20160304:161438.281 cannot process json request: Can't open JSON object or array "null,"clock":1457108078}"

Do you know how can I figure out this ?

Thanks!

Thank you for trying zaws!
Are each instances running ?
This tool can get CloudWatch data for only running instances.
Please check your CloudWatch data.
https://console.aws.amazon.com/cloudwatch/home?region=us-east-1#

[ike-dai]

If you can, please send me zabbix_server.log.
dai.ikd123@gmail.com

And, please send screen capture (Configuration->Hosts->->Discovery->CloudWatch discovery (EC2)).

Hello guys,

I'm getting the same error message: 1483:20161201:093657.760 cannot process json request: Can't open JSON object or array "null,"clock":1480606617}". Any updates about this topic?

Best regards!

Hi,
I am also getting the same error and I am running Zabbix server version 3.2.1-1 on Ubuntu 16.04 on Amazon EC2. The Zabbix Server time is in UTC

Error Message:

@ihernandezbm @ankush-grover-3pg Thank you for your reporting.

This error will be caused by not getting data from AWS CloudWatch API.
Please check AWS IAM user permissions.

Zaws calls CloudWatch ListMetrics API and GetMetricStatistics API.
These permissions are set your IAM user?
For example, please check the following command with your API Access key id and secret key.

aws cloudwatch list-metrics --namespace "AWS/EC2"

[ankush-grover-3pg]

Hi Ike-dai,
It is not related to Permissions because I can list the metrics through the command you have mentioned.

aws cloudwatch list-metrics --namespace "AWS/EC2" --profile ops-dev

"Metrics": [
{
"Dimensions": [
{
"Name": "InstanceId",
"Value": "i-xxxxxx"
}
],
"Namespace": "AWS/EC2",
"MetricName": "NetworkIn"
},
{
"Dimensions": [
{
"Name": "InstanceId",
"Value": "i-xxxxxxx"
}
],
"Namespace": "AWS/EC2",
"MetricName": "NetworkPacketsIn"
},
{
"Dimensions": [
{
"Name": "InstanceId",
"Value": "i-xxxxxx"
}
],
"Namespace": "AWS/EC2",
"MetricName": "DiskReadOps"
},

Thank you for your response, I really appreciate that. I'll will check what you mentioned and then will let you all know! Best regards!

Hi all,

It was my mistake, I didn't configured my credentials in Zabbix console, I mean that I ran "aws configure" and set the credentials, and everything started working!

Thank you so much!

Displays Json error!!!

@i got same error.
Just SSH'ed to zabbix (ubuntu), added AWS profile for user "ubuntu".. That pushed plugin to work!
But still there are messages in zabbix server log:
received invalid agent history data from "127.0.0.1": Can't open JSON object or array "null,"clock":1486563970}.. I use zabbix 3.2.

[ike-dai]

@valery-zhurbenko Thanks. zaws is executed with Zabbix Server process owner (default "zabbix").
Your zabbix-server processes will be running with "ubuntu" user.

About your error,
I want to know which item is error state.
Please check the following items and low-level-discovery rules status on your Zabbix Web dashboard.

• Item: cloudwatch stats monitor (EC2)
• Item: cloudwatch stats monitor (ELB)
• Discovery Rule: CloudWatch discovery (EC2)
• Discovery Rule: CloudWatch discovery (ELB)
• Discovery Rule: EC2 instance discovery
• Discovery Rule: ELB discovery

Hello,

I have the same error on zabbix 3.2.4:
25344:20170307:113123.590 received invalid agent history data from "127.0.0.1": Can't open JSON object or array "null,"clock":1488882683}"

Command aws cloudwatch list-metrics --namespace "AWS/EC2" works.

Somebody fix this issue?

TY
Jose Luis

Hi,
Sorry, I have not found the cause yet.
Please tell me about your error item or discovery rules.

• Item: cloudwatch stats monitor (EC2)
• Discovery Rule: CloudWatch discovery (EC2)
• Discovery Rule: EC2 instance discovery

[jl-sysmanager]

In Item: cloudwatch stats monitor (EC2)

Discovery rules works like charm.
