boto3 caught_exception botocore.exceptions.EndpointConnectio

[sgargano]

Dear all,

we have just installed boto3 as requested by the AWS Wizard.

The Wizard itself works perfectly, we were able to pass the credentials and any information requested.

But we got some error even launching manually the command:

Code: Select all

sudo ./check_ec2.py -P 5 --metricname CPUCreditBalance --instanceid 'i-xxxxxxxx' --accesskeyid 'ACCESSKEY' --secretaccesskey 'SECRETYKEY' --region 'eu-central-1b' --warning '100:' --critical '25:'

I tried to modify the Region to "eu-central-1" without "b" and I got this error:

Code: Select all

sudo ./check_ec2.py -P 5 --metricname CPUCreditBalance --instanceid 'i-xxxxxxxx' --accesskeyid 'ACCESSKEY' --secretaccesskey 'SECRETYKEY' --region 'eu-central-1' --warning '100:' --critical '25:'

Code: Select all

The check has received a response with no data. This is generally caused by an incorrect region name, invalid metric name, or invalid instance ID.
Please verify the following:
Region: eu-central-1
Metric: CPUCreditBalance
Instance ID: i-xxxxxxxxxxxxxxx

Currently all the information looks correct!
Do you have any suggestion or workaround to avoid those errors?

[scottwilkerson]

Are you 100% sure i-xxxxxxxxxxxxxxx is active AND in that region?

[sgargano]

Are you 100% sure i-xxxxxxxxxxxxxxx is active AND in that region?

yes they are,
should we enable some security rule from AWS or some API function for the metrics?

[sgargano]

./check_ec2.py -P 5 --metricname CPUCreditBalance --instanceid 'i-' --accesskeyid '' --secretaccesskey '' --region 'eu-central-1' --warning '100:' --critical '25:'
The check has received a response with no data. This is generally caused by an incorrect region name, invalid metric name, or invalid instance ID.
Please verify the following:
Region: eu-central-1
Metric: CPUCreditBalance
Instance ID: i-........

created a new user in aws for nagios to double check
but same issue..

[scottwilkerson]

Is this a Burstable Performance Instances? I believe these metrics are only available if they are

https://docs.aws.amazon.com/AWSEC2/late ... cw-metrics

[sgargano]

yes it is a t2 and we can see the metrics on CloudWatch.

[scottwilkerson]

The users do need permissions to cloudwatch in AWS, such as CloudWatchFullAccess policy

[sgargano]

yes we checked the user permissions and we are able to see the results by using the AWS cli:

Code: Select all

C:\Users\ss>aws cloudwatch get-metric-statistics --metric-name CPUUtilization --start-time 2019-05-28T10:18:00Z --end-time 2019-05-28T11:18:00Z --period 3600 --namespace AWS/EC2 --statistics Maximum --dimensions Name=InstanceId,Value=i-xxxxxxxxx

{

    "Datapoints": [

        {

            "Timestamp": "2019-05-28T10:18:00Z",

            "Maximum": 2.06896551724107,

            "Unit": "Percent"

        }

    ],

    "Label": "CPUUtilization"

}

[scottwilkerson]

The metric you were previously trying to get and failed was CPUCreditBalance not CPUUtilization

[sgargano]

[root@chlugmw1 ~]# aws cloudwatch get-metric-statistics --metric-name CPUCreditBalance --start-time 2019-05-28T10:18:00Z --end-time 2019-05-28T11:18:00Z --period 3600 --namespace AWS/EC2 --statistics Maximum --dimensions Name=InstanceId,Value=i-xxxxxxx
