According to the  Red Hat Customer Portal , to use RELP with Rsyslog, you need to install the rsyslog-relp package on both the server and the client. If the remote server does not have rsyslog-relp installed, RELP logging will not work as expected.

NTP  service needs to be configured to ensure logs, alerts and information is consistent across clusters that are located in different countries.  NTP stands for Network Time Protocol and it is used to synchronize the clocks of all the nodes in a cluster 1 .  This helps to maintain accurate timestamps for logs, alerts and other information that are generated by Nutanix clusters 1 .

inline compression  is a technique that compresses all incoming write I/O operations over 4 KB inline in the persistent write buffer (oplog) 2 3 .  This approach enables you to use oplog capacity more efficiently and helps drive sustained performance 2 .  From AOS 5.18 onward, inline compression (compression delay=0) is enabled by default for all new containers 2 4 .

Provision storage on the Nutanix cluster by creating a volume group. Create a client whitelist to enable access to the volume group by using the IP addresses or client initiator IQNs in a whitelist (as part of the volume group configuration). Create a secret for the volume group if you are using CHAP authentication.

According to the Nutanix Support & Insights web search result 1 , erasure coding is a data savings technique that utilizes stripes and parity calculation in a Nutanix cluster. Erasure coding increases the usable capacity on a cluster by reducing the replication factor of data blocks. Instead of replicating data, erasure coding uses parity information to rebuild data in the event of a disk or node failure.  Erasure coding can save up to 50% of storage space compared to replication factor 2, and up to 75% compared to replication factor 3 2 .

when you create a custom alert policy, you can choose between two types of thresholds: Static Threshold and Behavioral Anomaly. Static Threshold allows you to set a fixed value for the metric that triggers the alert. Behavioral Anomaly allows you to use machine learning to detect abnormal behavior based on historical data.

If you select Behavioral Anomaly as the threshold type, you cannot set a warning level for the alert. You can only set a critical level that indicates how much deviation from normal behavior is considered an anomaly 3 . Therefore, the Alert warning if field is greyed out when you select Behavioral Anomaly.

This is because Nutanix uses a distributed storage fabric (DSF) that replicates data across multiple nodes and drives to ensure data resiliency. When a drive fails, the cluster detects the failure and initiates a data rebuild process to restore the replication factor (RF) of the affected containers. The data rebuild process does not affect the availability or performance of the VMs, as they can still access their data from other replicas on other nodes or drives. Therefore, there is no need to wait for 60 minutes, use a shared volume group, or trigger an HA event.
