Well, it's not really "pretty" yet (as a dashboard) but MQTTool for IOS works, "not bad"... and it's totally free.
I changed the PHP script around a bit to publish all the "Load Averages" (in one message) and all the "Wuhan Coronavirus Stats" (in one message) and subscribed to both of them. In the "Load Average" app, there is the one, five and fifteen minute server load averages (very handy if managing a server, obviously) and in the "Wuhan" app, there are the C (confirmed cases), the S (suspected cases), the D (deaths) and R (recovered cases). You can easily start to image the myriad way to use MQTT for you own private "things" network from this short tutorial, I think.
BTW, I am still searching for a good "dashboard" app for MQTT (for either IOS or macOS), but no joy yet.
When you think about it. MQTT is "the only way to go" if you are developing these kinds of private "IoT" app, every devices can be both a publisher and a subscribe, and if you run your own private MQTT server, you do not have to worry about a third parties mining your data.
Hello,
I'm facing a big problem with my hosting server (Dual Xeon 2.4GHz), I'm having a load in the CPU usage and the memory (maybe it's related) ALSO mySQL:
Server Load 5.34 (2 cpus) (to 22 sometime)
Memory Used 68.4 % (to 70% sometime)

Hi all
what are the ways by which we can know and generate a report of the space remaining, memory(ram) used and the load on the server over a period of time. (1 Reply)
we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)

Hello I am running a liferay application in tomcat on one of my hosted linux machine having 4GB of ram and 1 CPU.
I get the tomcat response really slow and with much digging I found that the cpu might be loaded and can be tracked with top command.

pset_getloadavg
pset_getloadavg(3C) Standard C Library Functions pset_getloadavg(3C)NAME
pset_getloadavg - get system load averages for a processor set
SYNOPSIS
#include <sys/pset.h>
#include <sys/loadavg.h>
int pset_getloadavg(psetid_t pset, double loadavg[], int nelem);
DESCRIPTION
The pset_getloadavg() function returns the number of processes assigned to the specified processor set that are in the system run queue,
averaged over various periods of time. Up to nelem samples are retrieved and assigned to successive elements of loadavg[]. The system
imposes a maximum of 3 samples, representing averages over the last 1, 5, and 15 minutes, respectively.
The LOADAVG_1MIN, LOADAVG_5MIN, and LOADAVG_15MIN indices, defined in <sys/loadavg.h>, can be used to extract the data from the appropri-
ate element of the loadavg[] array.
If pset is PS_NONE, the load average for processes not assigned to a processor set is returned.
If pset is PS_MYID, the load average for the processor set to which the caller is bound is returned. If the caller is not bound to a pro-
cessor set, the result is the same as if PS_NONE was specified.
RETURN VALUES
Upon successful completion, the number of samples actually retrieved is returned. If the load average was unobtainable or the processor
set does not exist, -1 is returned and errno is set to indicate the error.
ERRORS
The pset_getloadavg() function will fail if:
EINVAL The number of elements specified is less than 0, or an invalid processor set ID was specified.
The caller is in a non-global zone, the pools facility is active, and the specified processor set is not that of the zone's
pool.
