Es scheint, als wäre dies das, was Sie wollen. Ich habe die erste Abfrage aktualisiert, um das richtige ANSI JOIN zu verwenden Syntax und dann für die zusätzlichen zwei Abfragen wurden sie über einen LEFT JOIN verbunden auf stats_host Feld:
SELECT s.stats_host,
h.host_name,
s.stats_avgcpu,
s.stats_avgmem,
s.stats_avgswap,
s.stats_avgiowait,
s7.7dayavgcpu,
s7.7dayavgmem,
s7.7dayavgswap,
s7.7dayavgiowait,
s30.30dayavgcpu,
s30.30dayavgmem,
s30.30dayavgswap,
s30.30dayavgiowait
FROM sar_stats s
INNER JOIN sar_hosts h
on s.stats_host = h.host_id
INNER JOIN sar_appgroups a
on h.host_appgroup = a.group_id
and a.group_name = 'Pervasive'
INNER JOIN sar_environments e
on h.host_environment = e.env_id
and e.env_name = 'Staging 2'
LEFT JOIN
(
SELECT s.stats_host,
AVG(s.stats_avgcpu) AS '7dayavgcpu',
AVG(s.stats_avgmem) AS '7dayavgmem',
AVG(s.stats_avgswap) AS '7dayavgswap',
AVG(s.stats_avgiowait) AS '7dayavgiowait'
FROM sar_stats s
WHERE DATE(stats_report_time) BETWEEN DATE_SUB(curdate(), INTERVAL 8 DAY) AND DATE_SUB(curdate(), INTERVAL 1 DAY)
GROUP BY s.stats_host
) s7
on s.stats_host = s7.stats_host
LEFT JOIN
(
SELECT s.stats_host,
AVG(s.stats_avgcpu) AS '30dayavgcpu',
AVG(s.stats_avgmem) AS '30dayavgmem',
AVG(s.stats_avgswap) AS '30dayavgswap',
AVG(s.stats_avgiowait) AS '30dayavgiowait'
FROM sar_stats s
WHERE DATE(s.stats_report_time) BETWEEN DATE_SUB(curdate(), INTERVAL 31 DAY) AND DATE_SUB(curdate(), INTERVAL 1 DAY)
GROUP BY s.stats_host
) s30
on s.stats_host = s30.stats_host
WHERE DATE(s.stats_report_time) = DATE_SUB(curdate(), INTERVAL 1 DAY);
