I am attempting to set up Zingchart using the PHP wrapper module.
Server:
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial
Running as a VM under VMWare
I am receiving an error with the example code when calling the ZC->connect method.
Thus:
<HTML>
<HEAD>
<script src="zingchart.min.js"></script>
</HEAD>
<BODY>
<h3>Simple Bar Chart (Database)</h3>
<div id="myChart"></div>
<?php
include 'zc.php';
use ZingChart\PHPWrapper\ZC;
$servername = "localhost";
$username = "nasuser";
$password = "password";
$db = "nas";
$myQuery = "SELECT run_time, time_total from stats";
// ################################ CHART 1 ################################
// This chart will use data pulled from our database
$zc = new ZC("myChart", "bar");
$zc->connect($servername, "3306", $username, $password, $db);
$data = $zc->query($myQuery, true);
$zc->closeConnection();
$zc->setSeriesData($data);
$zc->setSeriesText($zc->getFieldNames());
$zc->render();
?>
</BODY></HTML>
Error:
# php index.php
PHP Fatal error: Uncaught Error: Class 'ZingChart\PHPWrapper\mysqli' not found in /var/www/html/zc.php:69
Stack trace:
#0 /var/www/html/index.php(22): ZingChart\PHPWrapper\ZC->connect('localhost', '3306', 'nasuser', 'password', 'nas')
Line 69 is:
$this->mysqli = new mysqli($host, $username, $password, $dbName, $port);
Running:
# php -m | grep -i mysql
mysqli
mysqlnd
pdo_mysql
Seems to indicate that I have the relevant packages installed. Indeed, if I attempt a normal PHP connection it works:
<?php
$servername = "localhost";
$username = "nasuser";
$password = "password";
$dbname = "nas";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * from stats limit 10;";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "id: " . $row["stat_id"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
Output:
# php db.php
id: 1<br>id: 2<br>id: 3<br>id: 4<br>id: 5<br>id: 6<br>id: 7<br>id: 8<br>id: 9<br>id: 10<br>
Any ideas?
Thanks.
I've encountered the same problem!
There's kind of problem with import on the mysqli.
I changed the
$this->mysqli = new mysqli($host, $username, $password, $dbName, $port);
from ZC.php to
$this->mysqli = new \mysqli($host,$username,$password, $dbName, $port);
and worked.

When the script is executed simply by command line it says "everything ok"
But in nagios it shows error "CRITICAL - function 'xxx' is not registered in the server"
Thanks in advance
After spending long time on this, finally got the answer all that have to do is.
yum install nc
nc is what that was missing from the system.
With Regards,
Bankat Vikhe
Not easy to say but it could be related to your script not being executable as embedded Perl.
Try with # nagios: -epn at the beginning of the script.
#!/usr/bin/env perl
# nagios: -epn
use strict;
use warnings;
Be sure to check all the hints in the Perl Plugins section of the Nagios Plugin Development Guidelines
I\m unable to understand how to set gcAllowVeryLargeObjectsruntime param for worker role. I set this pram in app.config. But it doesnt work. As I understand I need to somehow config it in config file of wotker host.
Update: Final solution based on answer
ServiceDefinition.csdef
<WorkerRole name="XXX" vmsize="Standard_D4">
<Startup>
<Task commandLine="myStartup.cmd" executionContext="elevated" taskType="simple" >
<Environment>
<Variable name="yyy" value="yyy" />
</Environment>
</Task>
</Startup>
Next files should be added to worker project as content with Copy Local Always

i am using a perl script for unzipping a zip file by crontab. The script is working properly if i execute it manually. but whenever i set it in cron the script does not work any more. i have tested cron setting other script files are working from cron only this zip extracting script is not working .
Script is as follows :
#!/usr/bin/perl
use IO::Uncompress::Unzip qw(unzip $UnzipError);
$dir = '/root/perl';
open (han2, "ls -l $dir/*.zip |awk '{print \$9}'|");
#array1 = <han2>;
chomp(#array1);
for ($i=0;$i<=$#array1;$i++) {
$zipfile = $array1[$i];
$u = new IO::Uncompress::Unzip $zipfile
or die "Cannot open $zipfile: $UnzipError";
die "Zipfile has no members"
if ! defined $u->getHeaderInfo;
for ( $status = 1; $status > 0; $status = $u->nextStream) {
$name = $u->getHeaderInfo->{Name};
warn "Processing member $name\n" ;
if ($name =~ /\/$/) {
mkdir $name;
}
else {
unzip $zipfile => $name, Name => $name
or die "unzip failed: $UnzipError\n";
}
}
}
Crontab setting :
34 14 * * * /root/perl/./unzip.pl > /dev/null 2>&1
Please help me to do this task by cronjob
When cron executes your script, the current directoy probably won't /root/perl. Try chdir($dir) after you set $dir, or use full pathnames where required:
$u = new IO::Uncompress::Unzip "$dir/$zipfile"
or die "Cannot open $zipfile: $UnzipError";
mkdir "$dir/$name";
unzip "$dir/$zipfile" => "$dir/$name" ...
Changing to the correct directory is probably easier.
I have a Perl Script, which registers SNMP OIDs. With SNMP 1/2c, it is able to successfully register all OIDs. However, with SNMP V3, it only partially works.
As you see below, with SNMP V3, it is able to register "$root_OID.0.0.0" successfully. However, it timeouts when trying to invoke the java code for "$root_OID.0.0.1".
Does anyone know, why I'm able to make a successful java call in SNMP V1/2c, but not SNMP V3?
Many Thanks
