Amazon CloudWatchLogs putLogEvents in PHP gives error tooOldLogEventEndIndex

Question

I am trying to put Log on amazon CloudWatchLogs like this:

$response2 = $amzonLoger->putLogEvents([

            'logGroupName' => 'myGroup',
            'logStreamName' => 'myStream',
            'logEvents' => [
                [
                    'timestamp' => time(),
                    'message' => 'message'
                ],
            ],
            'sequenceToken' => lastToken,
        ]);
        var_dump($response2);

but always i've this response :

bject(Guzzle\Service\Resource\Model)#289 (2) { ["structure":protected]=> NULL ["data":protected]=> array(2) { ["nextSequenceToken"]=> string(56) "495401145812734324234234236420825819917076850" ["rejectedLogEventsInfo"]=> array(1) { ["tooOldLogEventEndIndex"]=> int(1) } } }

Can you help me understanding what does mean ["rejectedLogEventsInfo"]=> array(1) { ["tooOldLogEventEndIndex"]=> int(1)?

Answer 1

Cloudwatch API expects timestamp in epoch milliseconds, not seconds. Took me a while to figure that out. Thanks to the PHP snippet above.

Answer 2

Your error is telling you that the timestamp you are using is not good.

http://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_PutLogEvents.html

From doc:

None of the log events in the batch can be more than 2 hours in the future.
None of the log events in the batch can be older than 14 days or the retention period of the log group.

If using current time and current time is correct you may be in a different time zone (that is more than 2 hours ahead of UTC). Use UTC time for events timestamp.
