I have created the following script that returns the percentage of free space , the total space etc. of every disk for the remote servers the problem is that i want an extra column "warning" that prints No or Yes if the free space is bellow 10% i tried if statement but with no success. Please for your help.
Get-WmiObject Win32_LogicalDisk -filter "DriveType=3" -computer (Get-Content .\servers.txt) | Select SystemName,DeviceID,VolumeName,#{Name="Size(GB)";
Expression={"{0:N1}" -f($_.size/1gb)}},#{Name="FreeSpace(GB)";
Expression={"{0:N1}" -f($_.freespace/1gb)}},#{Name=" % Free(GB)";
Expression={"{0:N1}" -f(($_.freespace/$_.size)*100 )}},#{Name=" Warning";
Expression={????????}} |Format-Table -AutoSize |Out-File disk_monitor.txt
You can try something like
#{Name="Warning";Expression={ if((100 / $_.Size * $_.FreeSpace) -lt 10) { "Yes" } else { "No" }} };
This will calculate what percentage of disk space is available (100 / Size * FreeSpace) and if it's less than 10 (as in, percent), will return "Yes" or otherwise "No".

This is what I wrote to get output with powercli;
Get-VM -name SERVERX | Get-Annotation -CustomAttribute "Last EMC vProxy Backup"|select #{N='VM';E={$_.AnnotatedEntity}},Value
This is the output
VM Value
-- -----
SERVERX Backup Server=networker01, Policy=vmbackup, Workflow=Linux_Test_Production, Action=Linux_Test_Production, JobId=1039978, StartTime=2018-10-31T00:00:27Z, EndTime=2018-10-31T00:12:45Z
SERVERX1 Backup Server=networker01, Policy=vmbackup, Workflow=Linux_Test_Production, Action=Linux_Test_Production, JobId=1226232, StartTime=2018-12-06T00:00:29Z, EndTime=2018-12-06T00:0...
SERVERX2 Backup Server=networker01, Policy=vmbackup, Workflow=Linux_Test_Production, Action=Linux_Test_Production, JobId=1226239, StartTime=2018-12-05T23:58:27Z, EndTime=2018-12-06T00:0...
But I would like retrieve only "starttime" and "endtime" values
Desired output is;
VM Value
-- -----
SERVERX StartTime=2018-10-31T00:00:27Z, EndTime=2018-10-31T00:12:45Z
SERVERX1 StartTime=2018-12-06T00:00:29Z, EndTime=2018-1206T00:11:14Z
SERVERX2 StartTime=2018-12-05T23:58:27Z, EndTime=2018-12-06T00:11:20Z
How can I get this output?
This would be better suited in Powershell forum as this is just data manipulation.
Providing your output is always the same number of commas then
$myannotation = Get-VM -name SERVERX | Get-Annotation -CustomAttribute "Last EMC
vProxy Backup"|select #{N='VM';E={$_.AnnotatedEntity}},Value
$table1 = #()
foreach($a in $myannotation)
$splitter = $a.value -split ','
$splitbackupstart = $splitter[5]
$splitbackupend = $splitter[6]
$row = '' | select vmname, backupstart, backupend
$row.vmname = $a.AnnotatedEntity # or .vm would have to try
$row.backupstart = $splitbackupstart
$row.backupend= $splitbackupend
$table1 += $row
}
$table1
Untested. If you format of the string is going to change over time then a regex to search for starttime will be better.
I'm trying to automate snapshot checking DS free space. Its getting tricky for VMs with multiple DS attached. Script takes multiple snapshots for such VMs if condition satisfies. Please help me to understand where its going wrong.
Consolidating free space:
$free = (Get-Datastore -VM $vm | Select #{N="FreeSpace";E={[math]::Round(($_.FreeSpaceMB)*100/($_.CapacityMB),0)}})
Now checking if free space is available in each DS where VM connected:
foreach ($ds in $free.FreeSpace)
{
if (($ds -gt 25)
{
get-vm $vm | new-snapshot -name "$cmr.$date" -Description $description
}
}
If I understand the question properly, regarding dealing with multiple datastores... I would take a look at introducing a Sort-Object after the initial Get-Datastore which is based on the FreeSpaceMB property, then only selecting the first datastore (which should have the least amount of free space available) and performing your calculation based on that.
Untested example:
$free = (Get-Datastore -VM $vm | Sort-Object -Property FreeSpaceMB | Select-Object -Property #{N="FreeSpace";E={[math]::Round(($_.FreeSpaceMB)*100/($_.CapacityMB),0)}} -First 1)
I have a script which helps me to login to a cisco switch nad run the mac-address table command and save it to an array #ver. The script is as follows:
#!/usr/bin/perl
use strict;
use warnings;
use Net::Telnet::Cisco;
my $host = '192.168.168.10';
my $session = Net::Telnet::Cisco->new(Host => $host, -Prompt=>'/(?m:^[\w.&-]+\s?(?:\(config[^\)]*\))?\s?[\$#>]\s?(?:\(enable\))?\s*$)/');
$session->login(Name => 'admin',Password => 'password');
my #ver = $session->cmd('show mac-address-table dynamic');
for my $line (#ver)
{
print "$line";
if ($line =~ m/^\*\s+\d+\s+(([0-9a-f]{4}[.]){2}[0-9a-f]{4})\s+/ ){
my $mac_addr = $1;
print ("$mac_addr \n");
}
}
$session->close();
It get the following results:
Legend: * - primary entry
age - seconds since last seen
n/a - not available
vlan mac address type learn age ports
------+----------------+--------+-----+----------+--------------------------
* 14 782b.cb87.b085 dynamic Yes 5 Gi4/39
* 400 c0ea.e402.e711 dynamic Yes 5 Gi6/17
* 400 c0ea.e45c.0ecf dynamic Yes 0 Gi11/43
* 400 0050.5677.c0ba dynamic Yes 0 Gi1/27
* 400 c0ea.e400.9f91 dynamic Yes 0 Gi6/3
Now, with the above script I am trying to get the mac address and store it in $mac_addr. But I am not getting the desired results. Please can someone guide me. Thank you.
I'm not clear when you say you're not getting the desired results. I did notice that you are first printing your $line and then printing $mac_addr afterwards, besides that your expression seems to match.
Your regular expression matching your desired data.
If you simply just want the matches, you could do..
for my $line (#ver) {
if (my ($mac_addr) = $line =~ /((?:[0-9a-f]{4}\.){2}[0-9a-f]{4})/) {
print $mac_addr, "\n";
}
}
Output
782b.cb87.b085
c0ea.e402.e711
c0ea.e45c.0ecf
0050.5677.c0ba
c0ea.e400.9f91
If you want to print out the mac addresses, you can do the following:
/^\*/ and print +(split)[2], "\n" for #ver;
Note that this splits the line (implicitly on whitespace) if it begins with *; the mac address is the second element in the resulting list (in case you still need to set $mac_addr).
Hope this helps!
I have to check the free space on a disk volume and am using the command df -h, which produces this output:
Filesystem Size Used Avail Use% Mounted on
/dev/md0 27G 24G 2.1G 92% /
udev 506M 112K 506M 1% /dev
/dev/sda1 102M 40M 63M 39% /boot
This piece of script
my (#space, #freesp);
#space = grep /\/dev\/md0/,`df -h`;
print "#space\n";
is giving me
/dev/md0 27G 24G 2.1G 92% /
Which I can split on whitespace giving the values in $freesp[0], $freesp[1] etc.
But I want to remove or replace that G with white space, so that I can compare $freesp[3] with some value and can proceed with my script.
So what is the regex I have to use for this to happen, or is there any other better way to do this?
This code is working for me, but I'm looking in a direction I have mentioned.
#!/usr/bin/perl
use strict;
use warnings;
my (#space, #freesp);
#space = grep /\/dev\/md0/, `df`;
print "#space\n";
for (#space) {
chomp;
#freesp = split /\s+/, $_;
}
if ($freesp[3]/1024/1024 < 2.0) {
print "Space is less\n";
}
else {
print "Space is OK\n";
}
#print ($freesp[3]/1024/1024);
The real solution is not to use the -h option to df if you intend to parse the output with a script. That way, the output won't contain the "human-readable" K / M / G suffixes in the first place.
You may wish to instead use the -B1 option, which causes all sizes to be reported in bytes.
Edit: To answer the literal question, you could remove the suffixes and rescale the values appropriately like this:
my %units = (K => 2**10, M => 2**20, G => 2**30, T => 2**40,
P => 2**50, E => 2**60, Z => 2**70, Y => 2**80);
s/^(\d+(?:\.\d+)?)([KMGTPEZY])$/$1 * $units{$2}/e for #freesp[1 .. 3];
However, using the -B1 switch instead of -h would give the same result more easily, not to mention more accurately and reliably.
Hi all is there a way we can show progress bar for 10 minutes with statistics of percentage completed how much time remaining for 10 Minutes? using Write-Progress.
If I understand the question correctly the goal is to show some additional
information in the progress messages. This can be done for example by using the
Activity parameter. The script below only shows the idea (for 1 minute, for a
shorter test). It should be modified in order to reflect actually needed format
of the message and information to be shown.
$time = 60 # seconds, use you actual time in here
foreach($i in (1..$time)) {
$percentage = $i / $time
$remaining = New-TimeSpan -Seconds ($time - $i)
$message = "{0:p0} complete, remaining time {1}" -f $percentage, $remaining
Write-Progress -Activity $message -PercentComplete ($percentage * 100)
Start-Sleep 1
}
The progress looks like this:
57 % complete, remaining time 00:00:26
Processing
