Cluster mode powershell uptime reporting

[MAXWELL_CROOK]

Hi all

I'm in the infancy of powershell, i've managed to write 1 script so far that was pretty basic. However i've recently started down the route of trying to get a basic check in place. The check would be run via a script and would show if the nodes are up.

I cannot find a cmdlet of anything in get-ncnode or get-ncnodeinfo that would provide me with this as a starter.

Again, I may have missed this due to lack of knowledge but a nudge in the right direction would be greatly appreciated.

Thank you !

i'm not sure if you are looking for uptime or if the node is healthy, but they both should be in get-ncnode:

PS H:\> (get-ncnode).IsNodeHealthy
True
True

PS H:\> (get-ncnode).nodeuptime
2334190
2339855

Both to be honest! So thats really helpful, I keep forgetting that I can do a | fl and get all of the fields. Thanks for taking the time out to answer me. Appreciated.

no problem -

you can also use get-member to list all the object types/definitions. I use it all the time.

Thats great thank you, let me state what im trying to do as well.

Daily, certain checks are performed manually to ensure that the health of our Netapp estate is running without errors.

One of the checks thats perfomed is a

node run -node * -command uptime

This gives the following output for all nodes:

Node: yournodename

  3:58pm up 26 days,  2:41 162 NFS ops, 98270 CIFS ops, 0 HTTP ops, 11126647187 FCP ops, 0 iSCSI ops

What we monitor is the figures above increasing to ensure data is going through each node- we do this as we once had a situation where the nodes where up but no data was being sent or recieved - kind of a big problem! So I want to automate this but i'm really struggling with the powershell equivalent of the above.

[markweber]

try this:

get-ncperfdata -name system -instance system -counter hostname,uptime,nfs_ops,cifs_ops,http_ops,fcp_ops,iscsi_ops

you can get a list of all the counters in the system object with:

get-ncperfcounter system |select name

[MAXWELL_CROOK]

I must be doing something wrong as that gives me:

Name Uuid Counters

system uuid counters

system node1-01:kernel:system {cifs_ops, fcp_ops, hostname, http_ops...}

system node1-02:kernel:system {cifs_ops, fcp_ops, hostname, http_ops...}

system node1-03:kernel:system {cifs_ops, fcp_ops, hostname, http_ops...}

system node1-04:kernel:system {cifs_ops, fcp_ops, hostname, http_ops...}

[markweber]

no - that's correct.

the actual values are part of the counters property

they can be painful to work with (at least for me) - wrap the above in ( ).counters and you will see the values.

you can loop through them and create a custome object to make working with them easier

$data = get-ncperfdata -name system -instance system -counter hostname,uptime,nfs_ops,cifs_ops,http_ops,fcp_ops,iscsi_ops
$results = foreach($datum in $data){
    [PSCustomObject]@{
        "node" = ($datum.counters |where name -eq hostname).value
        "cifs_ops" = ($datum.counters |where name -eq cifs_ops).value
        "fcp_ops" = ($datum.counters |where name -eq fcp_ops).value
        "http_ops" = ($datum.counters |where name -eq http_ops).value
        "iscsi_ops" = ($datum.counters |where name -eq iscsi_ops).value
        "nfs_ops" = ($datum.counters |where name -eq nfs_ops).value
        "uptime" = ($datum.counters |where name -eq uptime).value
        "timestamp" = $datum.timestamp
        "timestampdt" = $datum.timestampdt
    }
}
$results | ft

 which should get you something like this:

PS E:\> $results | ft -AutoSize


node     cifs_ops fcp_ops http_ops iscsi_ops nfs_ops uptime   timestamp timestampdt

I am genuinely amazed with this, its beyond what I envisaged. Thank you so so much.

Certainly gives me a jump start with what i'm trying to achieve. Simply amazing.
