    RX-OK  : Correct packets received on this interface.
    RX-ERR : Incorrect packets received on this interface
    RX-DRP : Packets that were dropped at this interface and had to be re-sent (either successfully or not)
    RX-OVR : Packets that this interface was unable to receive. 
        RX-ERR,RX-DRP,RX-OVR should be < 0.1 % for RX_OK

        TX-XXX   are the statistics for sending data
        TX-ERR,TX-DRP,TX-OVR should be < 0.1 % for TX_OK
Flags:
    B – Broadcast
    M – Multicast
    R – Running
    U – Up
    O – ARP Off
    P – Point to Point Connection
    L – Loopback
    m – Master
    s - Slave

For Cluster Interconnect check UDP statistics
Udp:
    96168 packets received
    0 packet receive errors
For TPC connection check for bad segments and segments retransmitted  
Tcp:
    3933 segments received
    3919 segments send out
    0 segments retransmited
    0 bad segments received.

  1. nice article, just i have a question, when i tried to run de OSwatcher on solaris, the next error is appearing:

    oswbb heartbeat:Tue Nov 24 11:13:14 CST 2015
    ld.so.1: expr: fatal: libgmp.so.3: open failed: No such file or directory
    ld.so.1: expr: fatal: libgmp.so.3: open failed: No such file or directory
    .
    .
    .

    do you know any about it ??

  2. Sorry I don’t have access to any Solaris box .
    libgmp seems to be GNU MP portable library written in C for arbitrary precision arithmetic

    Can you find libgmp.so on your system ?
    If yes does your LD_LIBRARY_PATH point to that directory ?
    Is this a Solaris 10 Sparc system ?
