SWAP drive Alerts in vROps

In our MS SQL environment we use dedicated swap drive wich almost is full becouse of we set it up Custom size. Despite of it is a normal behavior, vROps generate “Guest file system space usage” Alert. In this article I would like to show you how to manage this situation in vRealize Operation Manager and avoid unnecessary alerts.

In this example we have two similar VM with three drive: C: for OS, H: for Kernel and S: for SWAP. From Kernel drive you could figure out, it is a SAP environemt 🙂

SWAP_Alert_vRealize_Operation_001

We want to keep alert to C: and H: drive, but we don’t get alert from S: (swap) drive, unless it is full.

First of all we can create new symptoms to this VMs. You can see the table below. Create Warning (85%) , Immediate (90%) and Critical (95%) symptom to C: and H: drive too. As you can see in table.

For S: drive enough Info level and condition will be “is greather than or equal to” with value 100 (precent). So the swap drive is full, vROps will create an Alert. 100% is just an advice, you can change the value as you wish, customize your environment.

SWAP_Alert_vRealize_Operation_003

We can use “Guest File System stats / Guest File System Usage (%)” metric under effected drive. As you can see, in this list we don’t see S:\ drive.

In the interest of we see our VM’s S:\ drive click the little grey icon next to Metrics select list form.

In the new window you can find a list of all VMs, select that VM wich want to configure, and click OK, than you can see the all drive under Guest File System stats.

Choose drive eg. C:\ and under the drive letter you will find the “Guest File System Usage (%)” metric. Drag and drop to right side of window.

Create all symptoms from list of below.

 

 

 

 

SWAP_Alert_vRealize_Operation_004

Create this Symptomes

Base Object Type Metrics Threshold Name Level Condition Value
vCenter Adapter / Virtual Machine Guest File System stats / C:\ Guest File System Usage (%) Static C Drive space usage at Warning level Warning is greather than or equal to 85
vCenter Adapter / Virtual Machine Guest File System stats / C:\ Guest File System Usage (%) Static C Drive space usage at Immediate level Immediate is greather than or equal to 90
vCenter Adapter / Virtual Machine Guest File System stats / C:\ Guest File System Usage (%) Static C Drive space usage at Critical level Critical is greather than or equal to 95
vCenter Adapter / Virtual Machine Guest File System stats / H:\ Guest File System Usage (%) Static H Drive space usage at Warning level Warning is greather than or equal to 85
vCenter Adapter / Virtual Machine Guest File System stats / H:\ Guest File System Usage (%) Static H Drive space usage at Immediate level Immediate is greather than or equal to 90
vCenter Adapter / Virtual Machine Guest File System stats / H:\ Guest File System Usage (%) Static H Drive space usage at Critical level Critical is greather than or equal to 95
vCenter Adapter / Virtual Machine Guest File System stats / S:\ Guest File System Usage (%) Static S Drive space usage at Info level (SWAP) Info is greather than or equal to 100

From this symptoms we can create new Alert.

Create new Alert

Name Base Object Type Impact Criticality Alert Type and Subtype Wait Cycle Cancel Cycle
SAP LFP Apps virtual machine guest file systems are running out of disk space vCenter Adapter/Virtual Machine Health Symptom Based Virtualization/Hypervisor: Capacity 1 1

If you did everything right, you will see similar things as picture below.

SWAP_Alert_vRealize_Operation_002

Create new Custom Group

Ok, now you can create a new Custom group under Environement / Environment overview menu. Hit the green cross on top of the menu, and configure membership criteria. Part of Policy leave empty for now. In this eximpe I add exact VMs to this group. The name of the new group: “Disable SWAP drive alert”

SWAP_Alert_vRealize_Operation_005

Create new Policy

Go Administration / Policies / Policy Library and add new one. In the “6. Alert / Symptom Definitions” menu disable “One or more virtual machine guest file systems are running out of disk space” default alert, and Enable the newly created alert, in this case “SAP LFP Apps virtual machine guest file systems are running out of disk space”

SWAP_Alert_vRealize_Operation_006

In “8. Apply Policy to Groups” part select the custom group wich was created before, and click OK.

vRealize Operation 6.6 “hidden” enhancement

You can find lots of infomration about VMware vRealize Operation 6.6 or 6.6.1 release. You should have to read about new H5 User Interface, new DRS capability and new Dashbords.

But do not forget the small things. I really like (and nowhere find information about this enhancement) the full screen option especially on Policy window.

vRealize_hidden_enhancement_001

I use 24″ display even so when I had to modify something in the Policy, I can’t resize the window and it was annoying. In policy window we can manage batch of options like major badge treasholds, alerts, collected metric and so on. So you can jump here really offten, if you want to chenge anything in vROps you can do it here. I really missed something like feature, but looks like not only me 🙂

I discovered this option on Symtomps Definition window and Dashboard widget windows too.

Change vROps “Datastore is running out of disk space” precent centric alert

Datastores is an importent objects in every VMware environtment. Especially free space of Datastore. So I think we need collect information about free space and we want to get alert message when the free space is low or it is getting low on DS.

Fortunetly VMware vROps has a built-in alert message about this topic. Name of this alert is “Datastore is running out of disk space” wich alert send to Us e-mail when “Datastore space usage reaching “ALERT LEVEL” limit” (85/90/95%) and “Datastore space time remaining is low” symptom definitions meet the values.

VMware_vROps_Symptoms_Alert_002
Default Alert settings of Datastore is running out of disk space

As you remember in vROps Alerts is working different way as other monitoring tools (as I know, like Nagios).

vROps collect metrics from environment, in this case from Datastore through vCenter Server. We can create Symptome Definitions (Alert / Alert Settings / Symptom Definitions/Add (green cross)) from Metrics or Properties.

VMware vROps Symptoms

Alerts consists of symptoms. If symptoms reaching the level wich was seted up and match all conditions (Any / All logical separation) we have got Alert from vROps.

More informations about vROps Alerts:

Jump back to subject of this blog article. My problem was with default DS alert that we should have leave huge free spaces on big datastores becouse of this symptoms is watching free space in precent. Eg. I got alert from 8TB datastore despite of I had 700GB free space on this DS.

I created new symptom definitions:

Base Object Type: vCenter Adapter / Datastore
Metrics: Capacity / Available Space (GB)
Threshold: Static

Name Level Condition Value
Datastore Available Space reaching Warning limit Warning is less than or equel to 150
Datastore Available Space reaching Immediate limit Immediate is less than or equel to 100
Datastore Available Space reaching Critical limit Critical is less than or equel to 50

VMware vROps Symptoms

After I added this tree symptoms to “Datastore is running out of disk space” alert as new Self-Datastore objects by “Any” condition.

VMware_vROps_Symptoms_Alert_003

This alert mean: The DataStore free space is lower than 85% or 90% or 95% and 150GB or 100GB ot 50GB and Disk space time remaining <= 60 days we are going to get an Alert message from vROps.

VMworld Europe 2017 – First day experiences #vmworld

I would like to share my opinion and experiences about my first VMworld EU (Barcelona) happening 🙂

11/09/17 – We pick up our badge and look oround a little. We met Valentin Czuczumanov (Senior Engineer at VMware) and Nyitrai Csaba (VMUG Hungary leader)

12/09/17 – Becouse of morning rush hour in Barcelona we arrived at Keynote a little bit late. The CEO of VMware Pat Gelsinger @PGelsinger has already started the speach. Fortunetly I got a quite good place in the “arena”

In the vmvillage had big screen where can you see the live streem from next room 🙂

Pat Gelsinger show us how we are able to migrate our VMs from on-prem to cloud in Virtual Reality. It was a funny demo with Alan Renouf @alanrenouf.

VMworld 2017 Pat Gelsinger
Pat Gelsinger at VMworld General Session

End of the general session I had to run Hall 8.0 Room 21, becouse I scheduled lots of breakout session. Fira Gran Via is a big place but VMworld also is a big event.

I catched up my session “Implementing Advanced vSphere Features with Veeam Availability Suite” (#PBO3309BES) in the time. Here is my tweet and a picture from session.

The presenters Michael Cade from UK and Clinton Wyckoff show us what is new in Veeam v10, and end of the session they demonstrate benefit of itegration Veeam and vRealize Log Insight. They also talked about how we can backup encrytped VMs and why vVOL is better then VMFS perspective of snapshot base backups.

After this session I met my colluages at Lunch. Until lunch time I visited some booth. I hope tumorrow I can visit more as today. Fortunetly I can spoke Saurabh Chandrate, Solution Architect at Blue Medora, about our new Blue Medora pack introduction. If somebady don’t know Blue Medora pls. visit they website. They have solution packs to VMware vRealize Operation Manager, and we have extended our vROps environment with this capabilities.

My next session was VMware Cloud on AWS: Storage deep dive  with Ben Meadowcroft

We close this day at Barcelona vs. Juventus match (3:0)
