should g_hostname be defined somewhere ?

Still younot anymore developing your plugin, this plugin is not useable anymore from checkmk 2.2 . It's some pity, it was helping me a lot.

USAGE: agent_emcunity [OPTIONS] HOST
       agent_emcunity -h

ARGUMENTS:
   HOST                               Hostname or IP address of the target SP

OPTIONS:
  -h, --help                          Show this help message and exit
  -u USER, --user USER                Set the admin user
  -p PASSWORD, --password PASSWORD    Set the password for admin user
  --debug           

it seems even though we have cached the password in the emc bitlocker and can query the unity application passwordless we are using the username and password explicitly for each call. I this correct ( as I working back through the code so could well be wrong )

Agent:

• implement WATO ruleset to get rid of command line call and pass user and password via variables

Checks:

general:

• redesign the iterating over the agent output

emcunity_dpe:

• make use of temperature and power consumption output

emcunity_pool:

• implement own checkgroup and default_levels

emcunity_vmfs:

• implement own checkgroup and default_levels

emcunity_lun:

• implement own checkgroup and default_levels

emcunity_fs:

• implement own checkgroup and default_levels

Please make possible that we get one Check thats include all HostObjects as MultiLine with the coresponding status.

If one of the Hosts has an Status Warning the complete Check goes to warning.

The Multilineoutput:
Hostname OK
Hostname Warning
Hostname Critical

Get the Status of the Host :
uemcli -d XXX -u ‘XXX’ -p 'XXX' /remote/host show -brief

Some examples :

9: ID = Host_9
Name = XXXX-02
Description =
Tenant =
Type = host
Address =
Netmask =
OS type = Windows Server
Ignored address =
Health state = OK (5)
Health details = "The component is operating normally. No action is required."

8: ID = Host_8
Name = XXXX-01
Description =
Tenant =
Type = host
Address =
Netmask =
OS type = Windows Server
Ignored address =
Health state = Degraded/Warning (10)
Health details = "The host only has one path to the storage system. Add multiple paths between host and storage systems to establish redundancy."

I get a crash on 1 of 6 DataStores.
Exception is: "AttributeError ('NoneType' object has no attribute 'group')"

I´m on 2.0.0.p9 CME

I'm running this against a Unity 450F on Check_MK Enterprise v1.6.0p22 and frequently the service for CPU utilization and Temperature goes unknown for about 15 minutes or so. This happens basically every hour from what I can see. How can I troubleshoot this to identify what the cause is?

Hi,

we upgraded to 1.6 and realized that the check is not running.

We have two shiny new Unity 350F boxes. Monitoring with cmk 1.5p19 is working fine, but the service "Host Connections" crashes all the time. This error is gone after configuring host connections, so this is a very low poriority issue. I will try to fix this in the next week.

Hi, many thanks for your good work with chekc_mk and applicable check for EMC UNITY.
I can confirm conpatibility for Emc Unity 400VL.
I did a small update in the check emcunity_disk, where I have to shift disk by the name, the slot selection was not applicable, because the returned value was not unique.

def inventory_emcunity_disk(info):

parse info, no key needed for inventory

"Name" is automatically added

keys = [ "Name", "Serial number" ]
disks = emcunity_parse_info(info, keys)
for disk in disks:
    if disks[disk]["Serial number"] != "":
        item = disks[disk]["Name"]
        yield item, None

def check_emcunity_disk(item, params, info):

parse info, just get data we want for this check by defining the keys

keys = [ "Name", "Health state", "Health details", "Type", "Model"]
disks = emcunity_parse_info(info, keys)
for disk in disks:
    name = disks[disk]["Name"]
    if name == item:
        hstate = disks[disk]["Health state"]
        hdetail = disks[disk]["Health details"]
        model = disks[disk]["Model"]
        hddtype = disks[disk]["Type"]
return parse_emcstate(hstate), "%s, %s, Model: %s, Type: %s" % (hstate, hdetail, model, hddtype)

i have just tested this agent on our Unity500 and both emcunity_fs and emcunity_lun return "UNKNOWN - invalid output from agent or error in check implementation"

Hi again.
in Cmk 1.5.0p12
checks:

you need to change:

Hello,

is it possible to implement a FC Connection Status Check ?

thx

Hi,
just tried to work with version 2.2.1 of this check in Check_mk RAW 1.5.0p13 (emcunity-2.2.1.mkp) but is not working, I had to switch to the old version ( emcunity300-1.2.4.mkp )

Hello,
The downloads from EMC have been moved to https://www.dell.com/support/home/de-de/product-support/product/unity-300/drivers.
You will need the keyword search "uem cli" to find the correct downloads.

At the moment it is not possible to find or download the downloads without logging in to the Dell support page.

Maybe you can update these information on your readme.

kind regards

Marcel

when you say

The latest version of the cmk package does not work with cmk versions < 1.6.0.

what specifically is broken ?

Why do I ask ?

Our monitoring team are making threatening noises to migrate to 1.6 and I want to alert them of impact to plugin and effort to fix.

Hi,

one of my pools is degraded caused by a failed drive. But the pool state is still OK, I had expect a WARN state.

Service State: OK
Service Output: OK - 27.87% used (xx of xx TB), trend: +x GB / 24 hours, subscription: 64%, EMC State: Degraded/Warning (10) "The pool is currently degraded, and does not have enough spare space to initiate a rebuild. Replace the faulted drive, or add a drive of the same type and size or larger to the system."

I had a look into the check source, and it does not check the pool state. But this should be checked. According to the docs, the following health states are possible:

• Unknown (0) — Status is unknown.
• OK (5) — Working correctly.
• OK BUT (7) — Working correctly, but there could be a problem.
• Degraded/Warning (10) — Working and performing all functions, but the performance may not be optimum.
• Minor failure (15) — Working and performing all functions but overall performance is degraded. This condition has a minor * impact on the system and should be remedied at some point, but does not have to be fixed immediately.
• Major failure (20) — Failing and some or all functions may be degraded or not working. This condition has a significant impact * on the system and should be remedied immediately.
• Critical failure (25) — Failed and recovery may not be possible. This condition has resulted in data loss and should be remedied immediately.
• Non-recoverable error (30) — Completely failed and cannot be recovered.

My ENV

• cmk EE 1.6p13
• EMC Unity 350F 5.0.0.0.5.116
• cmk_emcunity 2.2.2

I am running checkmk on container . According to doc mentioned have to run uemcli on checkmk server so I had to install it on dockercm but could not find uemcli for unity for ubuntu . Can we install uemcli on docker host ?

1- first step is to run uemcli -d hostname -u username -securePassword -sslPolicy store /sys/general show
would you please say what is the next step ?

The check is not running with the new checkMK 2.0
