# Checking Thing Connection via Event Logs

Another very reliable, but more difficult method of checking if SIM card is connected to a network is to check out Thing Event Logs.

There are 2 main ways to check out Thing Event logs:

### Checking Thing Events Logs via self-service console:

1\.       Login to the Monogoto porta&#x6C;***.***

2\.       Go to **Things** section of the porta&#x6C;***.***

3\.       Select a Thing from the list of seen Things in the porta&#x6C;***.***

4\.       Use scroll bar, to scroll down to the end of the Thing Menu page.

5\.       Check Events section of the Thing Menu page.

### Checking Thing Events Logs via an API command:

To view Thing Events logs, please use following request:

```
curl -X POST "https://console.monogoto.io/thing/searchCDR" -H "accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer <<<_TOKEN_HERE_>>>" -d "{ \"ThingIdELK\": \"<<<_THING_ICCID_ID_>>>\", \"SeverityELK\": \"<<<_EVENT_SEVERITY_>>>\", \"gteTimestampELK\": \"<<<_GREATER_OR_EQUAL_TIMESTAMP_>>>\", \"ltTimestampELK\": \"<<<_LESS_TIMESTAMP_>>>\", \"EsDataTypeELK\": \"<<<_EVENT_DATA_TYPE_>>>\", \"MessageTypeELK\": \"s<<<_EVENT_MESSAGE_TYPE_>>>\", \"limit\": \"<<<_RESULTS_LIMIT_>>>\"}"
```

{% hint style="info" %}
Please note that the above shown command needs to be replaced with information: \
\&#xNAN;**<<<\_TOKEN\_HERE\_>>>** - replace with your token\
\&#xNAN;**<<<\_THING\_ICCID\_ID\_>>>** - replace with *ThingId\_ICCID\_ABC*, where *ABC* is your thing *ICCID*. Example: *ThingId\_ICCID\_8912372646888991*\
\&#xNAN;**<<<\_EVENT\_SEVERITY\_>>>** - replace with the severity of the Event you wish to be displayed.\
\&#xNAN;**<<<\_GREATER\_OR\_EQUAL\_TIMESTAMP\_>>>** - replace with the timestamp of date/time to show greater or equal date/time Events. Please enter date/time in epoch format with milliseconds. [You may use a converter that can be found following this link.](https://www.epochconverter.com/)\
\&#xNAN;**<<<\_LESS\_TIMESTAMP\_>>>** - replace with the timestamp of date/time to show less than entered date/time Events. Please enter date/time in epoch format with milliseconds. [You may use a converter that can be found following this link.](https://www.epochconverter.com/)\
\&#xNAN;**<<<\_EVEN\_MESSAGE\_TYPE\_>>>** - replace with the Event message type to be displayed. \
\&#xNAN;**<<<\_RESULTS\_LIMIT\_>>>** - replace with how many results you want to be displayed. Default when not using this line is 10 results.
{% endhint %}

{% hint style="warning" %}
Please note that only API command lines **<<<\_TOKEN\_HERE\_>>>** and **<<<\_THING\_ICCID\_ID\_>>>** are mandatory, others can be removed from API command if not needed
{% endhint %}

Example of request that will show last 50 Events for our Thing:

```
curl -X POST "https://console.monogoto.io/thing/searchCDR" -H "accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer eyJhb6IkpXVCJ9.eyJSb2xlIjoiVXN4lclByb2ZpbGVJZF9kZGM2MThhNC0wNTI1LTQ2MmUtYWN3NzhhMGQxYmbSI6Im4zgFkbWluIiwiQ3VzdG9tsbCwiVXNlcklkIjoiVklkXzg5Yj5Y2OGEyUtNDQThhLTEzZjA0MzJhZDE3YyINTAzgZmUtZGI51My00ZjRiLTktN2U5Yjc0ZWU1ZThlIiwiaWNzM3MjI5L2MDY3NTE2Mjl9.99aSLzP7kTgK6TZGW-xalrMu0GkW6viunt3XxbNng" -d "{ \"ThingIdELK\": \"ThingId_ICCID_8912372646888991\", \"limit\": \"50\"}"
```

Expected result will show 50 last Events for our Thing:
