    PRODUCT:

    TrueSight Capacity Optimization


    COMPONENT:

    Capacity Optimization


    APPLIES TO:

    TrueSight Capacity Optimization - 20.02, 11.x, 10.x



    PROBLEM:

    Gateway server status is showing offline on Gateway Manager and UNKNOWN status on Administration > System > Status
     
    This situation may occur after an upgrade or TSCO normal operations. The status of the gateway servers is offline and cannot connect to console message when trying any gateway related tasks.

    How can we bring the gateway server online?
     
    Gateway Server > Status = UNKNOWN (for both Gateway servers)
    installed on host "xyz-host1.abc.com" has been updated to UNKNOWN
    installed on host "xyz-host2.abc.com" has been updated to UNKNOWN
     

      Unable to list running manager runs on console  
    Connection refused  
    Unable to connect to console(s).  
    connection timed out 

     


    SOLUTION:

     

    Basic troubleshooting steps to test connectivity on port 10129 that runs GeneralManager service on the Gateway Server.

      
    Check port 10129 is enabled on Gateway server  
     
    netstat -an |grep 10129 
      
    Output:
    [root@gateway_server ~]# netstat -an |grep 10129 
    tcp        0      0 0.0.0.0:10129           0.0.0.0:*               LISTEN 

    Check the General Manager service is running on the Gateway server? Port 10129 belongs to this service. If port 10129 is enabled then try to telnet port 10129 from TSCO Application Server  
     
    telnet <GW server Hostname> 10129 
      
    Output:
    [root@application_server ~]# telnet gateway_server 10129 
    Trying 172.20.4.226... 
    Connected to gateway_server.bmc.com. 
    Escape character is '^]'. 

    If General Manager service is not running then start it manually:  
      nohup /usr/adm/best1_10.7.00/bgs/bin/GeneralManagerServer 10129 & 
      
    It is always useful to test connectivity from the local workstation and from  the Application Server having connectivity issues to the Gateway Server to make sure both endpoints are good in terms of network health.  

    Alternatives to telnet in case the program is not installed on the Server.

      

    Linux:

    (1) nc command

    nc -v <GW server Hostname> 10129 

    Output:
    [root@application_server ~]# nc -v gateway_server.bmc.com 10129 
    Ncat: Version 6.40 ( http://nmap.org/ncat
    Ncat: Connected to 172.0.0.111:10129.  

    (2) cURL command

    curl http://<GW server Hostname>:10129 --Make sure which http or https protocols are set (TSCO 11.3.01 and above). 

    Output:
    [root@application_server ~]# curl http://gateway_server.bmc.com:10129 
    <?xml version="1.0" encoding="UTF-8"?> 
    <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:BMCGM="urn:GeneralManager"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOAP-ENV:Client</faultcode><faultstring>HTTP GET method not implemented</faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope> 

    --or-- 

    curl -v telnet://<GW server Hostname>:10129  

    Output:
    [root@application_server ~]# curl -v telnet://gateway_server.bmc.com:10129
    * About to connect() to gateway_server.bmc.com port 10129 (#0)
    *   Trying 172.0.0.111...
    * Connected to gateway_server.bmc.com (172.0.0.111) port 10129 (#0)

      



    (3) BASH command

    cat < /dev/tcp/<GW server Hostname>/10129  



    Windows:

    Using   PowerShell on the machine 
       
    PS C:\> Test-NetConnection -ComputerName [system_name] -Port [port number] -InformationLevel Detailed Output:
