If everything else is working ok, I wouldn't worry about it. I see you're in Austin. Ping us if you have a more specific issue.

Dear Michael , 1. Do you think that it's a known issue in Amazon Linux ? If yes, I can install in CentOS 7 2. I am thinking about the issue when we replicate LDAP ? If the statistic is not correct, we will be lose the overview of the system usage Than you

It has nothing to do with the Linux distribution or LDAP server. Those stats are just one picture of activity. You still have web server logs and all your other standard network management tools. No one relies too much on those stats. BTW, if you are setting up a clustered deployment of Gluu, you should consider buying a support contract, so you can use [Cluster Manager](https://gluu.org/docs/cm/3.1.3/) which is provided under the [GLUU-SUPPORT](https://github.com/GluuFederation/cluster-mgr/blob/master/LICENSE) license. Keep in mind that clustered deployment will not be supported on the community forums. Also, LDAP replication is just one piece of a clustered Gluu deployment. You also have to think of: 1. HA for redis 2. Private key rotation (every 2 days for OpenID Connect) 3. Centralized logging 4. Ease of deployment If you want to schedule a call to discuss support plans, you can do so at [https://gluu.org/booking](https://gluu.org/booking) If you do not want to purchase support, I suggest you accept a 99.9% SLA--do a good job monitoring and backing up, and you can live with one server and still keep under 8 hours of downtime per year.

Thank you very much . I am still testing and evaluating for this.
