====== Troubleshoot the gateway ======


===== Useful logs =====

When configuring the gateway or when something unusual happens, most of the time, to understand the behaviour of the gateway it is advised to consult the logs.
Here is the list of the most useful logs:

  * ''/var/log/messages*'': These files are the main logs, they gather the traces of the firmware. They contain the boot traces, the network events, the hardware events, and many other traces.
  * ''/var/log/lora.log*'': Theses files contain the traces of the common packet forwarder (lorad and lorafwd). If you encounter LoRa issues, this is a good way to start. The verbosity of this log can be increased/decreased. Refer to the [[ wiki:lora:cpf#log_management |log management]] section.
  * ''/tmp/board_info.json'': This file contains information about the hardware of the gateway. It is generated at each boot time.\\
  * ''/tmp/calib_loraloc.json'' (**for Wirnet iBTS**): This file contains the calibration values specific to this gateway. It is generated at boot time.
  * ''/tmp/calib_rf.json'' (**for Wirnet iFemtoCell, Wirnet iFemtoCell-evolution and Wirnet iStation**): This file contains the calibration values specific to this gateway. It is generated at boot time.
  * ''/dev/nmea*'' (**Wirnet iBTS and Wirnet iStation**): These devices receive NMEA frames (GPS) every seconds. It can be monitored with the ''cat'' command. 

===== Useful commands =====

Since Kerlink gateways use a Unix system, most current commands are available (''ifconfig'', ''route'', ''ps'', ''iptables'', ...).

**KerOS specific commands:**
  * ''gsmdiag.py'': generates a status of the modem.
  * ''connmanctl'': used to configure/monitor the network manager.
  * ''opkg list-installed'': lists the installed packages.
  * ''monit status'': displays the status of the monitored processes.

===== Bootcause =====

The ''bootcount'' value is counting the number of reboots since the last power cycle.
At each power loss the counter is reset to 0. The maximum value of this counter is 65535.\\
The ''bootcount'' value can be checked in the file ''/tmp/board_info.json'':
<code bash>
# grep bootcount /tmp/board_info.json
        "bootcount": 1,
</code> 

When a gateway is started/restarted, U-Boot displays the boot cause.\\ 
The possible reasons are:

  * POR: Power On Reset (happens when the gateway is powered or after a powerloss).
  * WDOG: Watchdog.
  * SW: Software Reset.
  * HW: Physical reset (RESET button).
  * UNKNOWN: unknown cause.

This information is transmitted to initrd and to applications with the kernel argument « bootcause ». \\
The information is then provided in the ''bootcause'' parameter in the file **''/proc/cmdline''**. \\
Example:
<code bash>
# cat /proc/cmdline 
console=ttymxc0,115200 bootmode=nominal bootcause=SW bootcount=5 bootfail=0
</code>

===== Contacting Kerlink's support team =====

In case you need assistance to troubleshoot your gateway, Kerlink's support team will help you if:
  * The gateway is still under warranty.
  * The gateway has been bought directly from Kerlink.

If the gateway does not satisfy this requirement, please contact [[sales@kerlink.fr]]. Our Sales team will make you an offer to get assistance.

Otherwise, contact [[support@kerlink.fr]] to get assistance. Our support team will open you an account in Kerlink's ticketing tool.

When contacting the support team, to improve and speed up the resolution of your issue, please provide them:
  * The serial number of your gateway(s):
    * For Wirnet iBTS, the serial number is written on a sticker inside the case with "Wirnet iBTS" written on it.
    * For Wirnet iFemtoCell, the serial number is written on the rear sticker (it is named "Final product ID").
    * For Wirnet iStation, the serial number is written on the external sticker (it is named "Product ID"). 
    * For Wirnet iFemtoCell-evolution, the serial number is written on rear sticker (it is named "Product ID"). 
  * A precise description of your problem. "Gateway not working" is not enough to investigate.
  * The list of the actions you took to troubleshoot/investigate your problem.
  * The date of your problem.
  * The version of your firmware.
  * The logs of your gateway (refer to the automatic log gathering section). Without these logs, it is difficult to investigate. If you are able to reproduce the problem, make sure to reproduce it and gather the logs afterwards.
  * Any information that would help us understand the context. For example, if the gateway is on the field or in a lab, if a third party program is used, if the gateway was previously working, etc.

===== Automatic log gathering =====

To simplify the log gathering process, two scripts are available. These scripts generate an archive containing many logs and commands results.

++++Gathering logs from shell since release 4.2|

To gather the logs from shell:
  * Execute the command ''get_logs''. //The execution of the script takes less than 1 minute.//
  * It will generate an archive in the same directory you executed the script (example: ''Logs_2E0605F5_7b26_20200124-095206.tar.gz'')
  * Retrieve this archive (use whatever method you prefer: FileZilla, scp, ...).
++++

++++Gathering logs from shell on older releases|

To gather the logs from shell:
  * Upload the script bellow (use whatever method you prefer: FileZilla, scp, copy/paste, ...) in a folder of your gateway and go to this folder.
  * Convert the file to Unix text file format using ''dos2unix get_logs.sh''.
  * Add execution rights to the script using ''chmod 755 get_logs.sh''.
  * Execute the script using ''./get_logs.sh''. //The execution of the script takes less than 1 minute.//
  * It will generate an archive in the same directory you executed the script. (example: ''Logs_2E0605F5_7b26_20200124-095206.tar.gz'')
  * Retrieve this archive (use whatever method you prefer: FileZilla, scp, ...).

++++Gathering logs from USB (no commands required)|

To gather logs from a USB without typing any command:
  * Download the following script and copy it on a USB flash drive.
  * Create a ''usbkey.txt'' file on the USB flash drive as described [[wiki:keros_custo:sw_updates#specific_files|here]].
  * Plug the USB flash drive into the USB port of the gateway.
  * Wait for the yellow debug led fast blinking. //The execution of the script takes about 1-2 minutes.//
  * Unplug the USB flash drive.
  * An archive with all the required logs has been created on the USB flash drive.

===== Helium =====
This section contains some tips to do the first level of analysis (support level 1) on Helium gateways.\\
It will help you to investigate before escalate to Kerlink support (level 2).


**Please note that there is an existing open wiki for Helium users: [[https://wikikerlink.fr/helium|Kerlink Helium Hotspot Wiki]]**\\
  * First step is to follow [[https://wikikerlink.fr/helium/doku.php?id=home#troubleshooting_guide|Troubleshooting guide]] chapter which contains:
        * [[https://wikikerlink.fr/helium/doku.php?id=home#self_diagnostic|Self diagnostic]] section
        * [[https://wikikerlink.fr/helium/doku.php?id=home#useful_links|Useful links]] section

  * Second step, if necessary, is to follow the table below:

^ Source of info ^ KPI ^ Value ^ Action ^
^ [[https://helium-onboarding.kerlink.com/|Onboarding dashboard]] | Last seen | More than 30m ago | Gateway is offline. Ask customer to check power/internet. |
| ::: | ::: | Less than 30m ago | Gateway is online. Check next KPI. |
| ::: | Block height | = 0 | Gateway is downloading a snapshot. |
| ::: | ::: | = 1 | Gateway is loading the downloaded snapshot. |
| ::: | ::: | Else | KPI is ok, check next KPI. |
| ::: | Block age | > 30 mn | Gateway is syncing, check again in one hour. If it persists, you can open a ticket to Kerlink Support. |
| ::: | ::: | < 30 mn | Gateway is synced. Check next KPI. |
^ [[https://explorer.helium.com//|Helium explorer]] | 24h/14d earnings | > 0 HNT | Seems OK. Confirm with other Explorer KPIs. |
| ::: | Last activity date | < 3h | Seems OK. Confirm with other Explorer KPIs. |
| ::: | Is there a constructed challenge in the past 24h? | Yes | Seems OK. Confirm with other Explorer KPIs. |
| ::: | ::: | No | When gateway is synced, it should challenge. You can open a ticket to Kerlink Support. |
| ::: | Is there a challenged beaconer in the past 24h? | Yes | Seems OK. Confirm with other Explorer KPIs. |
| ::: | ::: | No | Gateway might be relayed. If not, you can open a ticket to Kerlink Support. |
| ::: | Is there a witnessed beacon in the past 8-24h? | Value depends on density around miner | Seems OK. Confirm with other Explorer KPIs. |
| ::: | ::: | No | You can open a ticket to Kerlink Support. |
| ::: | Is there a “broadcasted beacon” in the past 5d? | Yes | Seems OK. Confirm with other Explorer KPIs. |
| ::: | ::: | No | This is random but it seems odd. You can open a ticket to Kerlink Support. |

==== Gateways connected to a WMC====
For gateways connected to a WMC, you can use the Remote Command: Remote Access > Command\\
{{:images:remote_command_wanesy_management_center.png?800|}}
<note important>** Due its cryptographic key and to ensure Kerlink Helium Hotspot security, no SSH access can be given to those gateways. \\     **</note>

You can use commands below:
^ Command ^ Awaited result ^ 
| opkg list | {{:images:opkg.png?400|}} |
| monit status miner | {{:images:monit_status_miner.png?400|}} |Status = OK | 
| monit status lorafwd_helium | {{:images:monit_status_lorafwd_helium.png?400|}} | Status = OK |

If the result is different than the awaited result, you can open a ticket to Kerlink Support.
