Fluentd error: Unable to push logs to [elasticsearch]

-
After application deployments, Kibana stopped showing logs exactly after 7 days. The error "Fluentd error: Unable to push logs to [elasticsearch]" was shown in the fluentd logs. The initial response was to increase the buffer limits for fluentd as follows: chunk_limit_size 10M queue_limit_length 256 The behavior occurred again after two weeks, which led to the same error. On closer investigation, the error was preceded by the statement "Failed to write to the buffer." This led me to inspect the fluentd configuration again and found the following code in the buffer part which caused the fluentd buffers to be filled as per the official documentation on Fluentd : overflow_action block The fix for this overflow_action is to change from block to drop_oldest_chunk, allowing the fluentd logs to flow seamlessly to the elastic search by dropping the oldest logs in the buffer.   <buffer> @type file path /var/log/fluentd-buffers/kubernet...

SharePoint 2013 Installation Error: The current server cannot be joined to this farm

-
I got this error while running the SharePoint Product Configuration Wizard
An exception of type System.InvalidOperationException was thrown. Additional exception information: The current server cannot be joined to the farm because the set of installed products does not match the products installed in the farm.
I looked at the logs and found this error:
The current server cannot be joined to this farm because the set of installed products does not match the products installed in the farm. The license state for the current server doesn’t match the farm’s license state.
After validating the current and new servers products I found that the product key that was provided was for a SharePoint Enterprise and the current one was running Standard Edition. In order to join a server to the farm you need to have the same products installed on the new server.

Here is a quick way to validate the products installed on a server:

1. Run regedit

2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\15.0\WSS\InstalledProducts

3. The product GUIDs are as follows:


C5D855EE-F32B-4A1C-97A8-F0A28CE02F9C – “SharePoint Server 2013”
B7D84C2B-0754-49E4-B7BE-7EE321DCE0A9 – “SharePoint Server 2013 Enterprise”
9FF54EBC-8C12-47D7-854F-3865D4BE8118 – “SharePoint Foundation 2013”

4. Replace with the necessary product GUID.

5. Enjoy

On-board Linux computers to Azure Log Analytics

For on-boarding linux servers to Azure log analytics, just execute the command on the respective server: wget https://raw.githubusercontent.com/Microsoft/OMS-Agent-for-Linux/master/installer/scripts/onboard_agent.sh && sh onboard_agent.sh -p [protocol://][user:password@]proxyhost[:port] -w <YOUR WORKSPACE ID> -s <YOUR WORKSPACE PRIMARY KEY> In few cases like mine, the servers will not have access to internet and we will need to install the downloaded oms agent package with the proxy information.  sh omsagent-1.6.0-42.universal.x64.sh --install -w <YOUR WORKSPACE ID> -s <YOUR WORKSPACE PRIMARY KEY> -p [protocol://][user:password@]proxyhost[:port] The proxy can have username and password for authentication and even if no proxy authentication is required, we will need to enter a dummy username and password which in the example below is azure and azure. sh omsagent-1.6.0-42.universal.x64.sh --install -w <YOUR WORKSPACE ...

Office 365 User unable to book room on-premise in Exchange Hybrid environment

-
In a federated environment, an Office 365 user was unable to book meeting in room which was on-premise. After tracing the messages created for booking the room, it was confirmed that the message indeed reached but the room was rejecting it for some reason. The room was rejecting the meeting request as it was considering the Office 365 user as an external user. So to solve this, we need to run the following command in the On-premise Exchange environment if we want to allow all the rooms: Get-Mailbox | where {$_.RecipientTypeDetails -like "Roommailbox"}| Get-CalendarProcessing | Set-CalendarProcessing -ProcessExternalMeetingMessages $true For single room, run the following command: Get-CalendarProcessing -Identity <Room name> | Set-CalendarProcessing -ProcessExternalMeetingMessages $true  Now the Office 365 user will be able to book the on-premise meeting room. (This is assuming that the free/busy calendar sharing is already enabled in the federated environme...
